Compute the pressure due to a volume of gas.Controller: lodmore
Compute the pressure due to a change in volume of gas, based on the adiabatic expansion
- The follow graph show the change pressure when an initial 2m3 air is expanded or contracted:
- The units for pressure and volume can be interchanged with SI or Imperial systems, so long as the units used for p1 are the same as those in p2; and equally the units of v1 = v2. i.e. You are consistent.
p1 The initial pressure [psi] v1 The initial volume [ft3] v2 The new volume [ft3] gamma The gas constant. Default value = 1.4 (for air)
- The new pressure at volume v2. [psi]
