Beat the Summer Heat - What Size A/C Do I Need?

A larger air conditioner will not always provide more cooling. It should be sized for the room area. If properly sized it should operate long enough to remove moisture from the air. It is the moisture removed from the room which actually produces the feeling of cooling. Unfortunately many people in their rush to purchase a window air conditioner buy too large a model.

Too large a unit can actually provide less cooling than a smaller, properly sized unit. This is because with an oversized air conditioner its run time is too short. Consequently it does not remove enough moisture from the room to produce a feeling of comfort. If youre A/C seems to cycle off and then back on every few minutes and does a poor job of cooling, it is probably oversized for the room.

Air conditioners are rated in BTUs. british Thermal Units are a measurement of how much heat is being transferred form the room being cooled to where the heat is dumped out of doors. This is why the cooing coil inside the room is cool to the touch, while the part that hangs outside is extremely hot.

A window air conditioner used in the average household room can be as low as 4000 BTU. While 5000, 6000, and 8000 are the most common sizes purchased.

How do I determine what size A/C I need? Following is a basic sizing chart for calculating the window air conditioner needed for a room. Calculate the size of the room by multiplying the width of the room by the length of the room. Use your room size to determine what BTU's are required to cool that particular room size.

room in sq ft-----room in sq m-----A/C size in BTU's

100 250............9 23............5000 6000

250 400...........23 37............6000 8500

400 550...........37 51............8000 11000

550 875...........51 81...........11000 15000

Based on a room occupied by two adults, having an average insulation, number of windows, and sun exposure.

Which is the best room for placement of an air conditioner?

Wherever it gives the most comfort is where it should be installed. If you only have one air conditioner then we usually suggest the bedroom. This is because most people find that if they can sleep comfortably during a hot summer night then their next days work will be a lot easier. Getting through a hot day at work becomes a lot easier when you know you will sleep comfortably that night.

Some people do not like a cool sleeping environment so they will tend to place it in a living room or family room. Or some people will place it in the family room because the whole family can sleep there. Get out the sleeping bags and turn it into an adventure for the young ones. Beats waking up in the morning to find a dog, cat, and four kids in the bed with you.

Also window air conditioner can be noisy, which may disturb sleep. Others find the drone of the fan actually promotes sleep because all the neighbourhood noises are drowned out. Some people say the air conditioner works as well as a sleeping pill

But whichever room you eventually pick dont expect the impossible from youre A/C. It is not meant to cool more than one room or one open area. Air conditioners will not cool other rooms? This is because the blower in a window air conditioner is not very powerful. It is sized to cool one open area, not a number of interconnected rooms. Therefore once again a couple of smaller units may be better for your home than one large unit.

Lastly, remember to properly secure the air conditioner in the window. Once installed a piece of wood to stop the window from being lifted up is a good idea. If you have wooden sills the simple addition of a wood screw at the top of the raised window (the one you had to raise to install the A/C) will only take a minute. Otherwise an intruder could gain access to the house by lifting the window and letting the A/C fall out. This could result in the loss of both your valuables and the air conditioner.

Mysteries of Muscle Memory

When you learned to write, you trained the muscles in your arm and hand to create letters. It took time and concentration to do this, but with repetition it became automatic. Your hand developed muscle memory; when you write your name, your muscles remember how to move without focusing on the process.

Dancing, yoga, gymnastics and weight training are examples of other activities that require enhanced muscle memory. We can make the learning process easier and help establish muscle memory by using a few simple techniques:

* Visual images
* Repetition
* Slow motion
* Micromovement

Imagery

Using a visual image is an effective way to train your body to perform a new dance step or exercise. The best visual images are those which are familiar and detailed.

In dance, visualizing a movement helps you perform the step. For example, if a dancer wants to make an S-curving motion with her body, she can visualize a fish swimming, a camel walking, or a snake crawling. Since the best visual images are familiar and detailed, visualizing the color, texture, shape and markings of the image make it more vivid and effective. Likewise, visualizing yourself correctly repeating a new dance step or exercise makes the learning process easier.

many people find geometric shapes helpful. For example, you can imagine drawing a big circle to make learning a belly dance hip circle or circle step easier. A square is a useful image for learning a box step or hip square.

Repetition & slow motion

Repetition helps fix a new exercise or dance movement in your mind, so that the next time you perform it, you remember it more easily and perform it with less effort. Slow repetitions of a new exercise or dance step enable you to feel every nuance of the movement.

Rushing through a movement before youve completely mastered it skips over the important process of sensing every nuance of the movement; beginning dance students and exercisers often need to be reminded to slow down. Going slowly helps your muscles recognize precisely what the movement should feel like when performed correctly.

Micromovement

Micromovement means performing a movement in a very tiny way, using the least range of motion possible. For example, if you were writing the letter O ten inches high and then writing o in a script so tiny it could barely be seen, your O would require a much larger hand movement than tiny letter o, the micromovement. Using a tiny range of motion helps you sense subtle muscle movements which are occurring, but micromovements must be performed with awareness to get the full benefit. Going slowly helps.

Have fun with learning!

Select the movement or exercise you are working on, then answer the following:

Imagery: what animal, shape or object does it remind you of?
Repetition: what kind of music would help you when practicing this movement?
Slow motion: how many counts does it take you to complete one repetition?
Micromovement:what is the smallest range of motion you can use for the movement?

What Are the 39 Types of Sharks Known to Harm Humans?

What are the 39 types of sharks known to harm humans? Well, as soon as you read this question, your mind probably started racing, your heartbeat became more rapid and your throat dried out. The question that probably consumes your thoughts right now is: Are there that many dangerous species of sharks out there?

Well, calm down. Yes there are 39 types of sharks known to have harmed humans but only three species were actually involved in unprovoked shark attacks. No, Jaws itself, better known as a Great White shark was not one of these species. Surprised? In fact, out of 1190 shark attacks between 1580 and 2005, there were only 3 provoked shark attacks, one being fatal. Each of the following species was involved in one shark attack: the Hammerhead shark, the Blue shark and the Shortfin Mako shark. The fatal attack was done by the Hammerhead shark.

So according to the ISAF (International shark Attack File) between 1580 and 2005, there were 1187 unprovoked shark attacks done by 36 types of sharks. In fact, 17 of the 36 species involved in unprovoked shark attacks were responsible for 5 shark attacks or less. These types of sharks are: the Galapagos shark, the Tope shark, the Silvertip shark, the Spiny Dogfish shark, the Tresher shark, The Bignose shark, the Smooth Dogfish shark, the Basking shark, the Horn shark, the Sixgill shark, the Whale shark, the Greenland shark, the Whitetip Reef shark, the Porbeagle shark, the Leopard shark, the Mako shark and the Great Hammerhead shark.

Of the remaining 19 types of sharks known to harm humans, 6 types of sharks are responsible for 6 to 9 unprovoked shark attacks. These are the following species: the Grey Reef shark, the Oceanic Whitetip shark, the Sandbar shark, the Sevengill shark, the Dusky shark and the Silky shark.

Of the 13 types of sharks that are left, 3 species are responsible for 14 to 19 unprovoked shark attacks. These are the following types of sharks: the Spinner shark, the Blacktip Reef shark and the Bronze Whaler shark.

Of the 10 types of sharks that have been involved in 23 to 27 unprovoked shark attacks on humans, you have the 3 following shark species: the Lemon shark, the Caribbean Reef shark and the Wobbegong shark.

Now you have the top ten sharks that have been known to attack humans, 7 species are responsible for unprovoked shark attacks while 3 species that were mentioned earlier on this page have been involved in provoked shark attacks. The 7 species are: the Great White shark, the Tiger shark, the Bull shark, the Sand Tiger shark, the Requiem shark, the Nurse shark and the Blacktip shark.

The top 10 species are: the Great White shark (#1), the Tiger shark (#2), the Bull shark (#3), the Sand Tiger shark (#4), the Requiem shark (#5), the Nurse shark (#6), the Shortfin Mako (#7), the Blacktip shark (#8), the Hammerhead shark (#9) and the Blue shark (#10). The numbers of shark attacks done by these species vary between 36 and 410.

As you can see, the 20% types of sharks involved in shark attacks may seem impressive but not as alarming as you may have thought at first.
