The absolute pressure inside a tank is 0.13bar, and the surrounding atmospheric pressure is 98 kPa. A Bourdon gage is mounted in the tank wall to measure the pressure, in kPa? Is this a vacuum or gage reading? b) (967)kJ of heat is transferred from the system to the surroundings when a closed system of mass (28)kg undergoes a process. During the process, 200kJ work is done on the system. If the initial specific internal energy of the system is 300 kJ/kg, Describe the process and determine the final specific internal energy, in kJ/kg? Neglect changes in kinetic and potential energy.

Question # 2 A gas of mass (4)kg undergoes a quasi-static expansion which follows a relationship p = a+bv, where ‘a’ and b are constants. The initial and final pressures are (1017) kpa and (217) kpa respectively and corresponding volumes are 0.2meter cubic and 1.2meter cubic. The specific internal energy of the gas is given by u=1.5 pv -85kJ/kg, where ‘p’is in kpa and ‘v’is in m3/kg. Describe the process involved in given system and calculate the net heat transfer and the maximum internal energy of the gas during expansion. (m3 means metercubic).
