Hello good Afternoon Sir, Permission, i have a question in my homework. The following bellow is question. Please advice. Thank you Regards,Irfan (Look at the picture above. What's a hw/hm?)
List energy transfer and conversion processes that will occur during the testing of the steam turbine. Include processes that contribute to the operation of the turbine (e.g. heat transfer from the combustion gases to the steam generator etc.) and ‘parasitic’ energy transfer or conversion processes that will reduce the thermodynamic efficiency of the turbine (e.g. conversion of mechanical energy to heat by friction in the turbine shaft bearings). Identify the sources of irreversibility in these processes.
