Two kilograms of Refrigerant 134a, initially at 200 kPa and occupying a volume of 0.11874 m3, undergoes a process at constant pressure until the volume has doubled. Kinetic and potential energy effects are negligible.
Designate a control system/volume in the above sketch showing the various energies crossing the boundary. Draw a qualitative P-V diagram for the process. Write the energy balance equation and simplify to a form that is directly applicable to the problem.
Calculate the boundary work done during the process, in kJ.
Calculate the amount of heat transfer for the processes, in kJ.
steam flows through a passageway and at a particular location the pressure is 3 bar the temperature is 281.48c and the
Calculate the specific weight of toluene at a place where the acceleration of gravity is 32.2 ft/s^2or 9.81 m/s^2. Express your answer in both lbf/ft^3 and kg/m^3. Repeat this for Mars whre the acceleration due to gravity is 37.5% of that on Earth.
