Consider atmospheric air at 25c and a velocity of 25 m/s flowing over both surfaces of a 1-m-long flat plate that is maintained at 125c. determine the rate of heat transfer per unit width from the plate for values of the critical reynolds number corresponding to 105 , 5 105 , and 106

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

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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
