Question:

Your boss would like to connect a high temperature and pressure stream of steam (from another unit at the plant site) to a turbine that will be operated adiabatically and will serve as an energy source for a small electric generator. The steam is at T1 = 600 C and P1 = 10 bar. The outlet conditions of the turbine must be T2 = 400 C and P2 = 1 bar. The inlet diameter to the pipe connecting to the turbine is 10 cm and the outlet diameter of the pipe from the turbine is 25 cm. None of these parameters can be changed. However, the mass flow rate of the steam into the turbine can be regulated. Your boss has asked you to determine what mass flow rate of steam should be used to obtain1040 kW of work from the turbine. Report your answer in kg/s.
