Answer ALL Questions

PART A (10 * 2 = 20 marks)

1.Define Quasi:Static

2.Write down the SPEE for reciprocating compressor.

3.Compare the SI and CI engines.

4.A gas turbine plant receives air at 1 bar and 2909K and compresses it to 5 bar.

If the temperature of air after compression. is 10000K; find the thermal efficiency of the turbine.

5.The boiler produces dry and saturated steam at 30 bar. steam expands in the turbine to a condenser pressure of 20 kPa. Calculate the thermal of Rankine cycle for these conditions.

6.Compare between impulse and reaction turbine.

7.Estimate the minimum work required to compress 1 kg of air from 1 bar 270C to 16 bar. in two stages, if the law of compression is PV1.25 Constant and the intercooling is perfect. Take R 287 J/kg'K.

8.Draw the T-s and p.h diagrams for the vapour compression cycle with dry saturated vapour after compression.

9. Consider a plane wall of thickness L. its left face at x = O, is at a Tl and right face at x = L is at temperature T2. The wall has no heat and, its thermal ' conductivity k is assumed constant. Find the T(x) in a wall.

10.Flow through pipe : D1 = 0.02 m, m = 0.01 kgl/s , mu= 910* 10^-6 Find the now is laminar or turbulent.
