Acentrifugal pump delivers 227 m^3 /hr of water from a source 4 meters below the pump centre line to a pressure tank whose pressure is 2.8 kg/cm2 . friction loss estimates are 2 meters in the suction line and 1 metre in the discharge line. the diameter of the suction pipe is 250 mm and the discharge pipe is 200 mm. find: a) the water horsepower b) the kw rating of the driving motor if the pump efficiency is 70%

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

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

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