1. A vertical cylinder fitted with a piston contains 5 (kg) of R134a at 12°C. Heat is transferred at constant pressure causing the piston to rise until it hits a set of stops at which point the volume is doubled. Additional heat is added at constant volume to raise the temperature to 70°C and pressure to 1.4 MPa. Sketch the process on Pv and Tv diagrams. Find the heat transfer and work done for both processes. Ignore kinetic and potential effects.

A piston-cylinder device initially contains CO2 at 200 kPa and 400°C and the total enclosed volume is 300 litres. Due to heat loss, the piston moves downwards to a position where it sits on a pair of stoppers and its final enclosed volume is 150 litres. Further heat loss leads to the pressure being reduced to 160kPa. Workout 1) the final temperature, 2) the total work done by CO2 and 3) the total heat transferred to CO2. Also make some comments on the result of heat. 4) Create a schematic p-v diagram of the process The following assumptions are to be made: CO2 is a perfect gas and its molecular mass is 44kg/kmol. The ratio of specific heat capacities, γ (gamma) is 1.3 The volume occupied by the stoppers is to be ignored. There is no leakage in the system There is no friction between the cylinder and piston walls and the piston moved slowly at the same speed therefore, no acceleration. For the conversion from Celsius to Kelvin, use 273 Use 8314.5 J/kmol.K for the universal gas constant

Two kilograms of water are contained within a piston and cylinder assembly, with a massless piston, acted upon by a linear spring and the outer atmosphere. Initially the spring force is zero and P1 = P0 = 100 kPa with a volume of 0.2 m3. If the piston just rubs the upper supports the volume is 0.8 m3 and T = 600 ° C. Now some heat is added until the pressure reaches 1.2 MPa. The final temperature, plot the processes on the P-V diagram and find the work that is done during the process.

The pressure in the cylinder must be 800 kPa for the piston to float. Now the valves open slowly and heat is transferred so that the water reaches a steady state of 250 ° C with the valves open. Find the final volume and final pressure, work, and heat transferred during the process.
