I am trying to determine the temperature of air in a compressed air distribution sytem after a pressure reducing control valve. The air should cool to the J-T effect but cannot locate data for the the J-T coefficient for air in the 0 to 100 degrees C range.
Perry's 6th edition, page 2-133 has this data. It's easier for me to email you a copy than trying to recopy it here, please drop me your email address either here or at testdog2000@yahoo.com
