Questions (page 2)

Section A

Q1.

(a) A non-flow quasi-static process occurs for which P = -3V + 16 bar, where V is the volume in m3. What is the work done when V changes from 2 \text m3 to 6 m3?

(b) Air flows steadily at the rate of 1 kg/s through an air compressor. The properties of air at entry are velocity 7 m/s, pressure 105 kPa, specific volume 0.95 m3/kg. The properties at exit are velocity 5 m/s, pressure 700 kPa, specific volume 0.19 \text m3/kg. The internal energy of the air increases by 95 kJ/kg, as it flows through the compressor. Cooling water in the compressor jacket removes heat from the air at the rate of 60 kW.
(i) Compute the rate of shaft work input to the air, in kW.
(ii) Find the ratio of inlet pipe diameter to outlet pipe diameter.

(c) Define specific speed of a turbine. Derive its expression in terms of speed, power and head.

(d) Explain what you understand by Similitude. Further, explain the following:
(i) Geometric Similarity
(ii) Kinematic Similarity
(iii) Dynamic Similarity

(e) Sketch and describe a natural circulation high pressure boiler.

Section A

Q2.

(a) A system at 500 K receives 7000 kJ/min from a source at 1000 K. The temperature of atmosphere is 300 K. Assuming that the temperature of the system and source remain constant during heat transfer, find out :
(i) The entropy produced during heat transfer
(ii) The decrease in available energy of source after heat transfer and increase in available energy of the system.
Show the process on the T-s diagram and mark the increase in unavailable energy.
