Mutah University Faculty of Eng Thermodynamics Final Exam. Prof. M. Abu-Zaid Date: 8-5-2018 Problem (1) A Submarine is cruising in the ocean at a dep of 1.03. The atmosphere pressure is 100 KPa. Determ of the submarine. (8 marks) th of 320 m. Salt water has a specific gravity ine the pressure on the top surface Problem (2) A Closed flexible container initially contains 1 kg of saturat expands along a constant pressure process until t (12 marks) ed water at 160 °c. The water er reaches 1 m the volume of the contain (a) Determine the final temperature of the water (b)Determine the work done by the water during the process (c) Draw the process on P-v diagram Problem (3) A Piston-cylinder device contains 5 kg of refrigerant 1 refrigerant is now cooled at constant p (10 marks) 34a at 800 KPa and 70 °C. The ressure until it exists as liquid at 15 °c. (a) Determine the amount o f heat transfer (b) Show the process on T-v diagram. (10 marks) Problem (4) Steam enters a turbine operating on SSSF process with m turbine develops a power out put of 100 KW. At the inlet, the pressure is 6 MPa, the temperature is 400 °c, quality is 0.9, and the velocity is 50 m/s. Determine the rate of heat transfer from the turbine (KW). ass flow rate of 4600 kg/hr. The and the velocity is 10 m/s. At the exit, the pressure is 10 KPa, the Problem (5) Air flows steadily through a diffuser. The inlet area of the diffuser i mass flow rate of air is 3 kg/s. At the inlet pressure is (10 marks) s 0.01 m2, and the 300 KPa and a temperature of 100 C. The diffuser is insulated. Determine the temperature of the air leaving the diffuser. GOOD LUCK 1 2.Explanation / Answer
Gauge pressure=(density) (acceleration due to gravity) (depth)
=1.03*1000*9.81*320
=3233376pa =3233.376kpa
Absolute pressure= gauge pressure+atmospheric pressure
=3233.376+100
=3333.376kpa
