Did some homework regarding previous discussions on this issue. The formula is called the Combined Gas Law. It is a combination of Boyle's Law and Charles' Law. P1V1/T1 = P2V2/T2 If we assume constant volume in the pipe, we can leave V out. Example: Pressure = 15 PSI, temp = 70 degrees. If temp changes to 50, what is the pressure? 15/70 = P / 50 P = (50 X 15)/70 P = 10.7 PSI |
