look at PV diagrams. A PV diagram is a graph of Pressure as a function of Volume. There are four different situations that you can expect to see shown in PV diagrams: 1. Isobaric: the gas is held at a constant pressure 2. Isochoric: the gas is held at a constant volume 3. Isothermal: the gas is held at a constant temperature 4. by ASD Adila · 2018 — For example, they tended to think of a curved P-V ...

Calculate the present value of each cashflow using a discount rate of 7%. Which do you most prefer most? Show and explain all supporting calculations! Cashflow A: receive $60 today and then receive $60 in four years. Cashflow B: receive $12 every year, forever, starting today. The PV diagrams for a thermodynamical system is given in the figure below. Calculate the total work done in each of the cyclic processes shown. Solution. In the case (a) the closed curve is anticlockwise. So the net work done is negative, implying that the work done on the system is greater than the work done by the system.

The VT diagram shows: In the segment AB the volume of the gas is directly proportional to the temperature. This means that in this phase the pressure is constant, it is an isobaric process. In the pV diagram it is represented by a horizontal line. We can see that the volume in the first phase (from A to B) increases.
