A throttling valve is used in an air conditioning system to reduce the pressure of refrigerant:

R134a as it flows from a condenser to an evaporator. The refrigerant enters the throttling valve at a pressure of 140psia and a temperature of 95F and leaves the throttling valve at a pressure of 80psia. Find

a) The exit temperature (in F)

b) The exit specific volume (in ft3/lbm)

c) The exit specific internal energy (in Btu/lbm)
