Water from a reservoir passes over a dam through a turbine and discharges from a 50.0-cm ID pipe at a point 65.0 m below the reservoir surface. The turbine delivers 1.100 MW. Calculate the required flow rate of water in m3/min if friction is neglected. (See Example 7.7-3.) If friction were included, would a higher or lower flow rate be required

On a average work day more than work place firs are reorted

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
