Steam enters a turbine with a pressure of 4826 kPa, u=2958kJ/kg, h=3263 kJ/kg, and a flow of 6.3 kg/s. Steam leaves with h=2232 kJ/kg, u=2102 kJ/kg, andρ=20.7 kpa. There is radioactive heat loss equal to23.3 kJ/kg of steam. Determine 

(a) The power produced; 

(b) The adiabatic work; 

(c) The inlet specific volume; 

(d) The exit velocity if the exit area is 0.464m².
