b) enters the turbine at a velocity of 70 m/s. The steam leaves the turbine at a point 2 m below the turbine inlet. The steam exits at atmospheric pressure and has a velocity of 100 m/s. The turbine delivers shaft work at a rate of 70 kW, the heat loss from the turbine is 4,000 kJ/hr. 1,000 kg/hr of superheated steam at 40 bar (abs.) and 350°C drives a turbine. The steam i. Draw a diagram of the system, outline assumptions and write the energy balance equation for the system. ii. Calculate the specific enthalpy of the steam leaving the turbine. ii. Calculate the temperature of the steam leaving the turbine.
