Two steam turbine A and B operate under the following conditions: Initial pressure: 17 bar; exhaust pressure: 0.046 bar. In turbine A, the steam is initially dry and saturated, whereas in turbine B it is initially superheated by 94.5 C. Calculate (a) Theoretical steam consumption, kg/kWh, (b) Theoretical thermal efficiency of the two turbines, (c) Percentage reduction in steam consumption due to super-heating, (d) Percentage increase in thermal efficiency due to superheating.
