Problem 7.7-1 the input to this circuit is the voltage source source voltage v ⁢ left-parenthesis t right-parenthesis equals 12 cosine left-parenthesis 30 ⁢ t right-parenthesis v the output is the current i left-parenthesis t right-parenthesis equals upper b ⁢ ⁢ sine left-parenthesis 30 t right-parenthesis ma. determine the value of the constant, b, used to describe the output current. b

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

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
