Arod of a certain material is 50 mm in diameter for the first 100 mm and 25 mm diameter for next 100 mm. calculate the diameter of the rod of the same material 200 mm long which will be able to absorb the same maximum amount of energy as the first rod. given that the yield strength for the material of the rod is 300 mpa, calculate the maximum amount of energy which could be absorbed by the stepped rod. (take e as 200 gpa).

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
