Q A horizontal piston-cylinder assembly contains 2.00 kg of a fluid. The assembly is fitted with both a heater and a paddle wheel. It is found that the fluid undergoes an expansion from state 1 to state 2. During the process, the paddle wheel transmits 16.4 kJ of mechanical energy (Wp.w.) to the fluid via mixing, and the heater supplies 83 kJ of thermal energy (Q) to the fluid. The specific internal energy changes from U1 = 2386.6 kJ/kg to U2 = 2409.1 kJ/kg during the process. Determine the work done by the steam on the piston during the process (Wpiston) (kJ).

A group is considering installing a solar power station and has asked you for your recommendation if it should be a photovoltaic system or a solar thermal system. At this stage you are asked not to include cost factors. The single point design condition they have given you is for an incident solar radiation on the collector of 550 W/m2, a surrounding temperature of 18 C. The dead state for this problem should be taken as To = 291 K, Po = 1 bar. You can perform your analysis at steady state conditions. In addition to determining the power output and first law efficiency of the options, you have been requested to determine the exergy destroyed for each of them. The photovoltaic system has an efficiency of 0.15 defined as the power output/incident solar radiation. The basic photovoltaic collector is 1.1 m2 and losses heat from both the front and back surface. The edge area can be neglected. The convective heat transfer coefficient is 10 W/m2 K. The inverter and signal…
