A stream of superheated steam at 3 bar and 500 c is sent to a chamber where cool liquid water is spraying so that the outlet stream is 100% quality saturated steam at 3 bar.

A)What is the mass flow rate of the cool water given: specific enthalpy of cool water is 242.2kJ/kg and 150kg/min of superheated steam goes into the chamber?

B) If a larger spray chamber is used and some heat is lost in the unit, calculate the heat given off every minute given 200 kg/min of superheated steam and 60 kg/min of cool water is produced in the outlet stream.
