Question

Problem 17-2: Determine the heat transfer required to cause a tank initially pressurized with air to discharge isenthalpically. The initial state inside the tank is 1500 psia, 100 F, 10 lbm. The final state is 14.7 psia and .098 lbm. Assume ideal gas behavior.

Answer 1

Isenthalpic process is the one in which the enthalpy entropy of the system remains constant. The process in which there will be sudden change in the pressure but there is no heat transfer and work done would be zero. One example of isenthalpic process is throtelling process in which the fluid flowing through a paasege encounters a suddenrestriction could be a sudden and large restriction like valve. The result of restriction is sudden drop in the pressure of the fluid as it is restricted to flow through the restriction. So there will be no heat transfer not work done.
