Question

A superheated steam at 10 bar absolute with 150 °C is fed to a boiler at rate of 200

kg/min. It is desired to produce new superheated steam at 250°C and 10 bar with rate of

407.42 kg/min that emerge at position of 50 m higher than the inlet stream by mixing the

inlet superheated steam at 10 bar absolute with a second stream of saturated steam at

10 bar and 207.42 kg/min. Determine the heat input to the boiler (kJ/s)
