ZQ7/ In one stage of a process for the
manufacture of liquid air, air as a gas at 4
atm absolute and 250 K is passed through a
long, insulated pipe in which the pressure
drops 3 psi because of frictional resistance
to flow. Near the end of the line, the air is
expanded through a valve to 2 atm
absolute. State all assumptions. Compute
the temperature of the air just downstream
of the valve.
