Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

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
Solve the problem and show the solution.Note: The answer is given on the bottom right side of the image, just show the solution on how to get it.Thanks!!!

Upvotes for a quick solution. Thanks for solving this question.
A four stage single acting air compressor running in an atmospheric at 87 KPa and 15 degrees Celsius has a free air delivery of 2,83 m³/min. The section pressure and temperature are 80 KPa and 32 degrees Celsius respectively, the delivery pressure is to be 7 MPa. The temperature at the start of compression in each stage is 32 degrees Celsius, take n=1.3 for all stages. Calculate : 1. The intermidiate pressure ratio in 3 decimal place 2.The intermidiate pressure at first, second and third stage in KPa 3. The mass flow rate in kg/min 4.The power input in KW
Consider a sealed can that is filled with 4.4 kg of water at 115 °C and P = 248 kPa. Now a leak develops, and the pressure in the can drops to the local atmospheric pressure of 100 kPa (Cp=4.23 kJ/kg.K). The vapor leaves the can as soon as it is formed. How much vapour will evapourate before the liquid water reaches its boiling temperature at atmospheric pressure.
