An imperfect turbine can be thought of as a perfect turbine and a valve. Consider steam entering a 66% efficient turbine at 1100 psia, 900°F which sees a pressure drop to 25 psia. 1) Find the exit state for the 66% efficient turbine 2) Replace the turbine with a 100% efficient turbine and a valve and determine the new exhaust pressure for the turbine.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
