For the propane, (a) show the process on a p-v diagram, (b) evaluate the work, in \(\mathrm{kJ} / \mathrm{kg}\), and (c) evaluate the heat transfer, in \(\mathrm{kJ} / \mathrm{kg}\).
ANSWER:Solution 51P
Step 1 of 6
Here, first we have to plot the p-v diagram of the constant-pressure process of a Propane system within a piston-cylinder assembly. Then we have to determine the work done and the heat transferred,in the system.
