1. Pressure x Volume = constant(provided the temperature remain constant)

=> P1 x V1 = P2 x V2, where P1 = ambient pressure, V1 = Initial Volume, P2 = End Pressure, V2 = End Volume

I think the compression process is fast and the temperature of the gas will rise. So the constant temperature assumption is invalid. Instead, an adiabatic assumption is a much better approximation. For an idea gas adiabatic process, PV^gamma = constant. The power factor, gamma, is 1.4 for air. Newton made a similar mistake when calculating the speed of sound.

It seems DLE did not carry your design to the market. This is very disappointing. Is there a way for us to apply your design?
