Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Question

A piston-cylinder device, with a set of stops on the top, initially contains 3 kg of water
at 200 kPa and x=0.7. Heat is now transferred to the water and the piston rises until it
hits the stops, at which point the cylinder contains saturated vapor water. Additional
heat is transferred until the pressure inside cylinder also doubled.
Required: Perform step by step energy analysis and determine:
a) The initial volume and the initial temperature
b) The final volume and the final temperature
c) The boundary work
d) The total heat transfer
e) Draw pressure-specific volume graph and label all data with respect to the dome.

A rigid tank whose volume is unknown is divided into two parts by a partition. One side of the tank contains an ideal gas at 927 deg C. The other side is evacuated and has a volume twice the size of the part containing the gas. The partition is now removed, and the gas expands to fill the entire tank. Heat is now applied to the gas until the pressure equals the initial pressure. Determine the final temperature of the gas.

(b) The steam is allowed to expand during the heating (e.g., in a piston/cylinder system) such that the pressure is constant. Hint: The steam is not an ideal gas under these conditions.
A 100L tank initially contains water at 100kPa and a quality of 1%. Heat is transferred to the water, raising the temperature and pressure.

Determine the total mass of water that flowed out and the total heat transfer.
