Common Data for Question 01 & 02

The inlet and the outlet conditions of steam for an adiabatic steam turbine are as indicated in the figure. the notations are as usually followed.

1. If mass flow rate of steam through the turbine is 20kg/s, the power output of the turbine (in MW) is                                                   

      (a) 12.157                                                           (b) 12.941

      (c) 168.001                                                         (d) 168.785

 

   2.  Assume the above turbine to be part of a simple Rankine cycle. The density of water at the inlet to the pump is 1000 kg/m³. Ignoring kinetic and potential energy effects, the specific work (in kJ/kg) supplied to the pump is                                                                                                                                                         

      (a) 0.293                         (b) 0.351                      (c) 2.930                         (d) 3.510
