##### How Do You Prove Air Has Volume?

· Air, and how it behaves and moves, is important to understand the basic processes that lead to weather.But because air (and the atmosphere) is invisible, it can be hard to think of it as having properties like mass, volume, and pressure — or even being there at all!

##### BTU Calculator

However, volume is a more accurate measurement than area for determining BTU usage because ceiling height is factored into the equation; each three-dimensional cubic square foot of space will require a certain amount of BTU usage to cool/heat accordingly. The smaller the volume, the fewer BTUs are required to cool or heat.

##### CALCULATION WORKSHEET: COMBUSTION AIR,

• Calculate the maximum appliance input. Step 3: • Calculate the required volume. Divide room volume (Step 1) by total/1000 (Step 2). • If less than 50, additional air is needed. • If greater than or equal to 50, no additional air is needed. Step 3: • Determine if additional air is needed. • If less than max., no additional air is .

##### Compressed Gas or AirStorage Volume

The storage volume for a compressed gas can be calculated by using Boyle's Law. p a V a = p c V c = constant (1). where. p a = atmospheric pressure (14.7 psia, 101.325 kPa). V a = volume of the gas at atmospheric pressure (cubic feet, m 3). p c = pressure after compression (psi, kPa). V c = volume of gas after compression (cubic feet, m 3)
