Determine the transfer function for a low pass filter with the following characteristics: -> a cutoff frequency of 100 khz-> a stopband attenuation rate of 40 db/decade.-> a nominal passband gain of 20 db, which drops to 14 db at the cutoff frequencywhat is the formula for h(s) that satisfies these requirements?

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
