In a rolling operation of a 8 inch thick aluminum plate (average fow stress nch andhe inch using a rolling mill with a maximum power of 2000 hp at 100 rpm. roll radius is 4 plate width is 6 inch. assume a coefficient of friction of 0.5. (1hp 33000 lb. ftlmin) 15 kpsi) to a 3 0 rpm. roll radius is 4 inch and the a. b. c. what is the maximum draft that you can achieve? what is the total power required to achieve the maximum draft per pass? what is the required number of passes?

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
