Water flows at the rate of 200 i/s upwards through a tapered vertical pipe. the diameter at marks(3) clo5) the bottom is 240 mm and at the top 200 mm and the length is 5m. the pressure at the bottom is 8 bar, and the pressure at the topside is 7.3 bar. determine the head loss through the pipe. express it as a function of exit velocity head.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

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
