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. https://unacademy.com/user/rurutujajb96- 9511

3. A reversed Carnot cycle refrigerator maintains a temperature of-5 C. The ambient air temperature is 35 C. The heat gained by the nefrigerator at a continuous rate is 2.5 kl/s. The power (in watt) required to pump this heat out continuously is

4. cop-12 268 Ti-T2308-268 CoP 67 CoP2 6,7 = 2.5x103 T2 26 8K

5. A closed system contains 10 kg of saturated liquid ammonia at 10 C. Heat addition required to convert the entire liquid into saturated vapour at a constant pressure is 16.2 MJ. If the entropy of the saturated liquid is 0.88 k]/kg.K, the entropy (in kJ/kg.K) of saturated vapour is

6. .Two identical metal blocks L and M (specific heat - 0.4 k]/kg.K), each having a mass of 5 kg, are initially at 313 K. A reversible refrigerator extracts heat from block L and rejects heat to block M until the temperature of block L reaches 293 K. The final temperature (in K) of block M is

8. Steam with specific enthalpy (h) 3214 k)J/kg enters an adiabatic turbine operating at steady state with a flow rate 10 kg/s. As it expands, at a point where h is 2920 kj/kg, 1.5 kg/s is extracted for heating purposes. The remaining 8:5 kg/s further expands to the turbine exit, where h 2374 k]J/kg. Neglecting changes in kinetic and potential energies, the net power output (in kW) of the turbine is
