The direction of rotation of a three-phase squirrel-cage induction motor depends on the a) residual magnetism in the squirrel-cage motor b) interaction of the stator and rotor magnetic fields c) design of the induction motor d) phase sequence of the voltage applied to the motor stator windings

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
