Chapter 7, Problem 7.103P

A condenser (heat exchanger) brings 1 kg/s water flow at 10 kPa quality 95% to saturated liquid at 10 kPa. The cooling is done by lake water at 20 degree Celsius that returns to the lake at 30 degree Celsius. For an insulated condenser, find the flow rate of cooling water.

The air conditioner in a house or a car has a cooler that brings atmospheric air from 30 degree Celsius to 10 degree Celsius, both state at 101 kPa. For a flow rate of 0.75 kg/s find the rate of heat transfer

A factory generates compressed air from 100 kPa, 17°C by compression to 800 kPa, 500 K, after which it cools in a constant pressure cooler to 300 K, (see Fig. P4.36). Find the specific compressor work and the specific heat transfer in the cooler. 1 2 3 Compressor -w. Compressor section Cooler section

9. Air is expanded from 400 kPa, 600 K in a polytropic process to 150 kPa, 400 K in a piston cylinder arrangement. Find the polytropic exponent n and the work and heat transfer per kg air using constant heat capacity.

Please don't provide handwritten solution .....

Please help me solve this as soon as possible, and I will surely leave you a like.
