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

1. Two tanks are connected by a valve. Tank A contains 2 kg of carbon
monoxide gas at 77°C and 0.7 bar. Tank B holds 8 kg of the same gas
at 27°C and 1.2 bar. Then the valve is opened and the gases are allowed
to mix while receiving energy via heat transfer from the surrounding.
The final equilibrium temperature is found to be 42°C. Determine (a)
the final pressure (b) the amount of heat transfer. Also state your
assumption.
[P,=105 kPa, Q = +37.25 kJ]

An insulated, rigid tank has two compartments, one 8 times as large as than the other, divided by a partition. At the beginning, the smaller side contains 4 kg of H2O at 200 kPa, 90 ∘C, and the other side is evacuated. The partition is removed and the water expands to a new equilibrium condition. Assume the surrounding conditions to be 100 kPa and 30 ∘C. Part A. Determine the irreversibility during the process. Part B. What-if scenario: What would the irreversibility be if the larger chamber was 80 times larger?
2) Two glass bulbs, one on the left with a volume of 2 liters and the other on the right with avolume of 6 liters, are connected to one another by a thin tube that is initially closed by astopcock. The bulb on the left has 0.1 moles of ideal gas, and the bulb on the right isevacuated. The system is in thermal equilibrium with the surroundings at 300K. When thestopcock is opened, the gas flows out to fill both bulbs. Calculate A for this process. If wewere to insert a propeller to extract work as the gas flows from left to right, what is themaximum amount of work that we could possibly extract?
