Question

2 kg of steam is initially at a pressure of 3 bar. The initial dryness fraction is such that when the steam has been heated at constant volume to 4 bar it is saturated. After this heating process the steam is compressed isentropically to 10 bar. Sketch the processes a T-sand p-vdiagrams

Answer 1

The process involves heating and compressing steam in a closed system. A T-s and p-v diagram can be used to represent these processes.

Step-by-step explanation:

The process described here involves the heating and compression of steam in a closed system. Initially, the steam is at a pressure of 3 bar and has a dryness fraction that allows it to become saturated when heated to 4 bar at constant volume.

This process can be represented as a line in the p-v diagram. After the heating process, the steam is compressed isentropically to 10 bar. This compression can also be represented as a line in the p-v diagram.

To sketch these processes on a T-s and a p-v diagram, you would plot the initial state of the steam, the line representing the heating process, and the line representing the compression process.
