For each of the following loop transfer function f(s), find the portion of the root locus on the real axis, asymptotes, the arrival and departure angles at any complex zero or pole, and the frequency of any imaginary-axis crossing. plot the sketch of the root locus based on above findings. verify your results using matlab. submit plots of your hand sketches and the matlab results.
a. f(s)=- s(s+1)(s +5)(8 +10)
b. f(s)=; s +2 s(s+1)(3+5)(8+10) (s+2)(s+6)
c. f(s)= (+1)(3+5)(s+10)

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
