  2. RUTUJA BOTHARA . Perusing B.Tech in Mechanical Engineering from Vellore Institute of Technology, Vellore. (2015-2019) e Cleared JEE Mains 2015 Cleared VITEEE-2015 with AIR 8718 Cracked HITSEEE-2015 with AIR 91 . Worked as a Career Counsellor in Teachers Academy (2016- 2018) and BOLO app. 9511

  3. Which one of the following pairs of equations describes an irreversible heat engine? (B) 60<0 and 0 c0 () > 0 and - oQ () > 0 and <0 an

  4. clausius inequality is d Q engine is ^re versible co Heat ir 4 dg =0 Heat engine is reversible d >o No+ Possible For ah irreversi ble proces

  5. -For a gas turbine power plant, identify the correct pair of statements. P Smaller in size compared to steam power plant for same power output Q. Starts quickly compared to steam power plant R. Works on the principle of Rankine cycle S. Good compatibility with solid fuel (A) P, (B) R, S (C) Q, R (D) P, S

  6. Gas turbines are compact and hence have low weight whereas steam plants have boiler and condenser making them bulky. Gas turbine can be started and shut down quickly whereas in steam plants boiler takes a lot of time to start. Gas turbine works on Brayton cyde Only liquid fuel or pulverized coal is used.

  7. A source at a temperature of 500 K provides 1000 kJ of heat. The temperature of environment is 27 C. The maximum useful work (in kj) that can be obtained from the heat source is IS

  9. A certain amount of an ideal gas is initially at a pressure pl and temperature T1. First, it undergoes a constant pressure process 1-2 such that T2 3T1/4. Then, it undergoes a constant volume process 2-3 such that T3 = T1/2, The ratio of the final volume to the initial volume of the ideal gas is (A) 0.25 (B) 0.75 (C) 1.0 (D) 1.5

  10. For Process -2 3 Ta = 3 TI At con Staht pressare

  11. An amount of 100 kW of heat is transferred through a wall in steady state. One side of the wall is maintained at 127 C and the other side at 27 C. The entropy generated (in W/K) due to the heat transfer through the wall is

  12. A diesel engine has a compression ratio of 17 and cut off takes place at 10% of the stroke. Assuming ratio of specific heats as 1.4, the air standard efficiency in %
