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.

E3.1. You must use the property data from the tables in the Appendix of your text to do this problem. The figure below illustrates a pressure cooker with the pressure relief valve removed. atm- 100 kPa V= 2 liter bottom 5% is filled with liquid water . The pressure cooker has an internal volume of V = 2 liters. Because the relief valve is removed, the contents are initially at atmospheric pressure, Patm = 100 kPa. The pressure cooker contains water in a two-phase state. The bottom 5% of the volume of the vessel is filled with liquid water while the remainder of the vessel contains water vapor. a) Determine the initial temperature of the water in the cooker. b) Determine the quality and specific volume of the water initially in the cooker. c) Sketch by hand a T-v diagram and label the initial state of the water (state 1).
