An alloy has a yield strength of 794 MPa and an elastic modulus of 109 GPa. Calculate the modulus of resilience for this alloy [in J/m3 (which is equivalent to Pa)] given that it exhibits linear elastic stress-strain behavior.

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

Acompressor receives the shaft work to decrease the pressure of the fluid. 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
