An open feedwater heater operates at steadystate with liquid water entering inlet 1 at 10 bar, 50oC. A separate stream of steam enters inlet 2 at 10 bar and 200oC with a mass flow rate of 16 kg/s. Saturated liquid at 10 bar exits the feedwater heater at exit 3. Ignoring heat transfer with the surroundings and neglecting kinetic and potential energy effects, determine the mass flow rate, in kg/s, at inlet 1
