An engine oil cooler consists of a bundle of 25 smooth tubes, each of length 2.5 m and diameter 10 mm. If oil at 300 K and a total flow rate of 22 kg/s is in fully developed flow through the tubes, what is the pressure drop, in bar, and the pump power requirement, in kW

What precautions should you take to prevent injuries when dealing with heavy loads?

During a steady flow process, the change of energy with respect to time is zero. 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
