WebThe compressibility factor (Z), also known as the compression factor, is a useful thermodynamic property for modifying the ideal gas law to account for the real gas behavior.[1] In general, deviation from ideal behavior becomes more significant the closer a gas is to a phase change, the lower the temperature or the larger the pressure. WebThe formula for adiabatic compression can be expressed in various forms i.e. in PV form, in TV form and as PT form, where P, V and T are pressure, volume and temperature respectively. The adiabatic compression in Pressure and Temperature form is given by: P 1-Ꝩ T ꝩ = Constant. The adiabatic compression in Volume and temperature form: tauranga tiny homes
