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.

A rigid, well-insulated tank contains a two-phase mixture of ammonia with 0.0022 ft³ of saturated liquid and 1.5 ft3 of saturated vapor, initially at p₁ = 70 lb/in². A paddle wheel stirs the mixture until only saturated vapor at higher pressure, p2, remains in the tank. Kinetic and potential energy effects are negligible. Determine the pressure p2, in lb/in², and the amount of energy transfer by work, in Btu. Step 1 * Your answer is incorrect. Determine p2, in lb/in². P2= i81.56 lb/in²

This question requires the use of the Thermodynamic Property Tables supplied asadditional material.In addition, for steam, the specific ideal gas constant = 461.5 J/kg KA closed system is comprised of pure water substance initially at a temperature of 500 C and a pressure of 20 MPa (state 1).The system undergoes an isochoric process whereby its pressure drops to 0.1 Mpa (state 2). (d) For state 1 evaluate the specific volume assuming the steam behaves as an ideal gas and comment on your result.
X Your answer is incorrect. A rigid tank whose volume is 4 m³, initially containing air at 1 bar, 295 K, is connected by a valve to a large vessel holding air at 6 bar, 295 K. The valve is opened only as long as required to fill the tank with air to a pressure of 6 bar and a temperature of 350 K. Assuming the ideal gas model for the air, determine the heat transfer between the tank contents and the surroundings, in kJ.
