# How do you convert water pressure to air pressure?

One foot of water at 4 degrees Celsius is equivalent to 816.2 feet of air at 15 degrees C.

### How to convert air flow into water flow?

If you have the air flow velocity and pressure drop for at least three points, plot the pressure as a function of the velocity; P=av2+bv. Use the trendline plotting function in Excel to get the two constants or solve the simultaneous equations for two of the points. Then convert the constant "a" from air to water by multiplying by the ratio of the water density to the air density, which is around "834". Convert the…

### Why the weather changes?

Is change because the air and the water and the resulting pressure. Is change because the air and the water and the resulting pressure. Is change because the air and the water and the resulting pressure. Is change because the air and the water and the resulting pressure. Is change because the air and the water and the resulting pressure. Is change because the air and water and the resulting pressure gradients stimelate.

### Why is water pressure stronger than air pressure?

Think of it this way, if you had a plastic bottle filled with water and you poked a hole in the side, would water squirt out or would air squirt in? If air squirted in, then the air pressure would have to be higher. But since we know that the water would squirt out, we know that the water's pressure must be stronger. Of course, this is under normal conditions. If you pumped the air…

### How do you convert feet of air pressure to feet of water depth IE use a waterproof electronic altimeter to measure water depth?

I'm sorry, but your question is so poorly crafted, it's very hard to interpret. Are you asking what device could be used to measure water pressure and depth? Or are you looking for a way to convert feet of air to feet or inches of water? One foot of water (at 4 degrees Celsius) is equivalent to 816.2 feet of air (at 15 degrees C).

### Why will water evaporate more slowly on humid days?

This effect is caused by the partial pressure of the water vapour in the air. The more humid the air, the more water vapour it contains and thus it has a higher partial pressure. This pressure tends to prevent water from evaporating. When the air is completely dry, there is no partial pressure from any water vapour and water will evaporate more quickly. The partial pressure of the water vapour plus the partial pressures of…

### How does air pressure changes altitude increases?

It decreases. Air pressure is simply the pressure of all the other air on top of it. As you increase in elevation, there is less air on top of you. Therefore, the air pressure is less. As your altitude decreases, there is more air on top of you, therefore, the air pressure increases. Same with water. As you descend, water pressure increases. More on top of you.

### Why does air exert pressure?

Air exerts pressure in the same way that water exerts pressure on a diver. Air has weight, and because we are at the bottom of a blanket of air that surrounds the earth, the weight of that air is pressing down on us (creating pressure). If you go under water, you'll feel the additional pressure created by the weight of the water above you.
