Sample Problem _____ /45 Name:________________________ A piston/cylinder device initially contains kg of air at kPa and . The air in the cylinder is constantly being stirred by a paddle wheel. The net paddle wheel work is kJ. Heat is transferred to the water in a polytropic process with to State 2, when the volume has tripled. A: (3 pts) Draw a control volume and label all of the energy transfer mechanisms to or from the cylinder. B: (2 pts) List the assumptions needed to find the heat transfer:
