Chapter 6, Problem 6.26P

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

THERMODYNAMICS A certain gas expand from 7ft3 to 23ft3 while the pressure remains constant at 17.5psia. Find the work nonflow in the system in BTU.

Q2: One mole of air at P: and temperature Ti is compressed at constant volume till its pressure doubled. Then it is allowed to expand reversibly and isothermally to the original pressure and finally restored to the originol temperature by cooling at constant pressure. Sketch the processes on a P-V and calculate the net work done by the

A piston/cylinder has a water volume separated in VA = 0.3 m³ and VB = 0.4 m by a stiff membrane. The initial state in A is 1000 kPa, x = 0.8 and in B it is 1500 kPa and 250°C. Now the membrane ruptures and the water comes to a uniform state at 200°C. What is the final pressure? Find the work and the heat transfer in the process. Po mp cb A:H2O B:H20
