A liquid nitrogen cooler is The goal of this system is to
cool the liquid nitrogen flow at State 1. This is accomplished by diverting a
portion of the liquid through an expansion valve. When the liquid passes
through the valve, it flashes into saturated liquid and saturated vapor in the
flash tank. The saturated vapor is drawn off the top and the saturated liquid
is used to cool the liquid flow using an in-tank heat exchanger. For the
conditions shown in Figure P6.14, determine the mass flow rate (lbm/hr) and
temperature (°F) of the liquid nitrogen at State 4, and the mass flow rate
(lbm/hr)
