Step 1

The quality of vapor is defined by the ratio of the mass of vapor to the total mass of the mixture. The mixture consists of water vapor and liquid water. The value of quality can be lies between 0 & 1. The value of quality is 0 means it is saturated liquid and the value of quality is 1 means the vapor is saturated.

Hence the quality of vapor is –
