A3-in.-diameter horizontal waterjet having a velocity of 94 ft/s strikes a curved plate, which deflects the water 180â° at the same speed.

ignoring the frictional effects, determine the force required to hold the plate against the water stream.

take the density of water to be 62.4 lbm/ft3 water jet 3 in.

vius the force required to hold the plate against the water stream lbf.

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)

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

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
