An out-of-control nuclear reactor core is being sprayed with 2 kg/s liquid water at 20°c for emergency cooling. the water impacts the reactor core and vaporizes. there is a release valve at the top of the reactor that maintains a pressure of 150 kpa gage pressure inside the containment vessel. if the reactor is filled with saturated steam vapor, find:

1) the rate of heat release by the reactor core

2) the volumetric flow rate of steam entering the pressure relief valve
