Does anybody know a good program for making diagrams like P,V and P,T etc. ?

Expert Solution

CASE 1 : If you have detailed information of the dependency of pressure on volumen , i.e you have table of P vs V (P vs T) etc, then you can use microsoft excel to plot the graph.

1. You fisrt need to make three columns in excel sheet - One of saturated liquid volume, second of saturated vapour volume and third of pressure at which previous volumes exist . Both line to be drawn in graph separatly and then connected together as common point is Critical Point . Here both lines will merge.

2. Click on INSERT and then Click SCATTER button and Click on scatter with smooth line and markers

3. Right click on chart area and select the columns required and name the chart

CASE 2 : When you know only the component for which you need to plot the diagram.

Use Aspen plus software

1. Use a heater block with input and output variable

2. Enter the component and stream specifications with your desired component

3. Enter the base model as STEAM-TA

4. Enter the block specification

5. Then click Model Analysis Tools and sensititvity and then input the details . Then fill VARY with type block , fill DEFINE - with the variable you need , fill TABULATE with the variable added earlier.

6. Get the results and plot the graph as discussed in CASE 1.

Using the relationship for internal pressure πT = T (∂P/∂T)V – P, show that for a gas that obeys a truncated virial equation of state: Z = PVm/RT = 1 + B(T)/Vm, the internal pressure may be approximated as πT ≈ RT2(Vm)-2∙(ΔB/ΔT). Estimate the internal pressure at 1.0 bar and also at 10.0 bar for a hypothetical real gas at 275K given that B(T) = -28.0 cm3⋅mol-1 at 250K and -15.6 cm3⋅mol-1 at 300K for this gas.

For each problem, sketch the appropriate process diagram on a T-v, P-v, or P-h diagram 4.60 : Steam exiting the turbine of a power plant passes through the insulated shell-and-tube heat exchanger condenser. The mass flow rate of the steam is 145 kg/s, and the steam enters the heat exchanger as a saturated mixture with a quality of 0.95 at 20 kPa. The steam exits the condenser as a saturated liquid at 20 kPa. Liquid cooling water is used to...
