|In response to Re: temperature s. pressure|
: 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
Thank you Jimbo
