11.  (a)Explain rankine cycle and derive the air standard efficiency with neat sketch.

(b)Explain diesel cycle and derive the air standard efficiency with diagram

12.  Explain briefly about modern layout of coal based power plant and explain the various circuits with neat sketch.

13.  Explain the methods of fuel and ash handling system in thermal power plant with neat sketch.

14.  Explain briefly about modern layout of diesel power plant with neat sketch.

15.  An engine working on constant volume cycle has the following data

Clearance volume=0.04m²

Swept volume=0.13m²

Pressure and temperature at the beginning of the cycle are 1.15bar and 120⁰c. Maximum pressure of the cycle is limited to 23 bar. Calculate the air standard efficiency, maximum temperature of the cycle and mean effective pressure.
