Consider a large metal part initially at the dead state. it is then lifted from the factory into a treating furnace. in the furnace, it is heated and then finally quenched. describe what happens during the various processes in terms of exergy increase/decrease.

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal
