1. write down the differential equation that vC(t) satisfies, keeping the L as an unknown. 2. Write down the characteristic equation of the differential equation you wrote in step 1. 3. Write down the discriminant of the characteristic equation in step 2. 4. The expression for vc(t) satisfies the differential equation you wrote in Step 1. From the format of vc(t), what can you conclude about the discriminant? What value should the discriminant be?

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

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
