Problem 3.30
A piston-cylinder device contains 0.85 kg of refrigerant- 134a at -10°C. The piston that is free to move has a mass of 12 kg and a diameter of 25 cm. The local atmospheric pressure is 100 kPa. Now, heat is transferred to refrigerant-134a until the temperature is 15°C. Determine (a) the final pressure, (b) the change in the volume of the refrigerant, and (c) the change in the enthalpy of the refrigerant-134a.

Part 1
The storage tank contains lubricating oil of specific gravity 0.86 In one inclined side of the tank,
there is a 0.48 m diameter circular inspection door, mounted on a horizontal shaft along the centre
line of the gate. The oil level in the tank rests 8.8 m above the mounted shaft. (Please refer table
01 for relevant SG, D and h values).
Describe the hydrostatic force and centre of pressure with the aid of a free body diagram of the
inspection door.
Calculate the magnitude of the hydrostatic force and locate the centre
of pressure.
