Weba compression process, where PV1.3 = constant, until the volume is 20% of the initial volume and the absolute pressure is 8.1 bar (State 2). During the compression process, 44.5 kJ of work is done on the air. The cylinder is fitted with a cooling water jacket all around its outer wall. The cooling water jacket contains 1.75 kg of liquid water.

Discharge is at 311 KPa. The changes in KE and PE are negligible. For each of the following cases, determine the final temperature and the work if the … WebFlow Process: Processes performed in the open systems are called as Flow-processes. Figure 2.9 shows a portion of steam power plant. High pressure steam enters the steam turbines at Section (I), expands and produces work output and then it leaves the turbine at section (2). For analysing the expansion process, 2-methods are used. WebDec 9, 2014 · In a non-flow process there is heat transfer loss of 1055 kJ and an internal energy increase of 210 kJ. Determine the work transfer and state whether the process is an expansion or compression. ... [Ans: -38 kJ] 6. 2 kg of air is heated at constant pressure of 2 bar to 500°C.
