1. The pressure is constant at 1Mpa how come it goes up after touching saturation vapor line.?Shouldn't it remain constant throughout?

Please look at the Tv diagram below:

2. Why quasi-static equilibrium is necessary for engine efficiency?

Thanks.

1. Where does it say the pressure is increasing?
2. A real process is not quasi static. It's an assumption made to make all the calculations easier.

Btw is this homework.

Thanks.

That graph is showing a temperature rise after it leaves the saturated-mixture region, the pressure is still constant.
