Problem- A turbine is used to generate 1500 kW power. Steam at 10 bar and 400C is expanded adiabatically to 0.5 bar to power the turbine. The steam exiting the turbine is cooled by removing heat at a rate of 1.25 x 10^10 J/hr to produce a saturbated liquid at 0.5 bar. (a) Calculate the rate of steam supply needed for the turbine (kg/hr). (b) Calculate the quality of steam leaving the turbine.

I am in need please provide me complete solution for the above problem so I can get right solution
