E.2 use the voltage divider rule to find the transfer function vo(s)/vi(s) of the circuit in fig. e.3(a). show that the transfer function can be made independent of frequency if the condition c1r1 = c2r2 applies. under this condition the circuit is called a compensated attenuator. find the transmission of the compensated attenuator in terms of r1 and r2.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
