A steam turbine is to operate on a simple regenerative cycle. Steam is supplied dry saturated at 40 bar, and is exhausted to a condenser at 0.07 bar. The condensate is pumped to a pressure of 3.5 bar at which it is mixed with bleed steam from the turbine at 3.5 bar. The resulting water which is at saturation temperature is then pumped to the boiler. For the ideal cycle sketch the process on the T-s diagram and calculate, neglecting feed pump work,The amount of bleed steam required per kg of supply steamThe thermal efficiency of the plantThe specific steam consumption

An insulated piston-cylinder device contains 4 L of saturated liquid water at a constant pressure of 200 kPa. Water is stirred by a paddle wheel while a current of 8A flows for 50 min through a resistor placed in the water. If one-half of the liquid is evaporated during this constant-pressure process and the paddle-wheel work amounts to 300 kJ, determine the voltage of the source. Also, show the process on a P-v diagram with respect to the saturation lines.
