Find the spray flow rate into the pressurizer of a PWR by
using a force balance around a closed loop. This loop starts from the inlet to
the spray line and includes spray line, spray valve, pressurizer, surge line,
hot leg, steam generator primary side, reactor coolant pump suction pipe,
reactor coolant pump, and reactor coolant pump discharge line. The spray valve
flow area and loss coefficient are Asp and Ksp,
respectively. For given height and elevations, find the spray flow rate and the
condition at which there is no spray flow.
