- 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).
