Question 1 (variation a) Five litres (5 L) of saturated water steam is contained in a piston-cylinder device and is kept at 100 °C. The piston is frictionless. Four litres (4 L) of the steam is in the saturated vapour state, the rest is in the saturated liquid state. Calculate: (a) Total mass of the steam. (b) The quality of the steam. (c) The amount of heat required to completely change the steam to saturated vapour. (d) Represent the process on a T-v and a P-v diagrams.

the question below is already answered in the photos that I provided I only want to ask how did it find the answersSaturated steam at a pressure of 25 psia is sprayed into a stream of moist air. The initial condition of the air is 55 dry-bulb temperature and 35 F de-point temperature. The mass rate of air flow is 2000 lb per min. Barometric pressure is 14.696 psia. Determine how much steam must be added in lb per min to produce a saturated air condition, b) the resulting temperature of the saturated air.my question here is:regarding of the solution pls elaborate how did it get w1 and h1 is it given in the psychrometric chart or it has a specific solution to follow
