Steam is used in the following adiabatic turbine system to generate electricity; 15% of the mass flow from the first turbine is diverted for other use.
How much work (in kJ/h) is generated by the first turbine which is 80% efficient?
How much work (in kJ/h) is generated by the second turbine which is 80% efficient?
Steam for the turbines is generated by a boiler. How much heat must be supplied to the boiler (not shown) which has 300 kg/h of flow? The stream entering the boiler is T = 170°C, P = 8 MPa. The stream exiting the boiler matches the inlet to the first turbine.
