Find the charge on the capacitor in RLC series circuit where L=5/3H, R=100,c=1/30F and E(t)=300v. Assume the initial charge on the capacitor is 0C and the initoal current is 9A. what happens to the charge on the capacitor over time?

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
