Calculate the maximum power (in W) that can be dissipated through the load resistor RL in a DC circuit with voltage source V=28 V, internal resistance Ro=35 Ω and load resistor RL. Express the answer to one decimal place. (Use the equation given in part 2 in the manual. Know that the maximum power is when the load resistance equal to the internal resistance.)

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

Most leaks in reciprocating air compressors can be detected and minimized by: (clo4) a)-detecting leakage areas using ultrasonic acoustic detector. b)-tightening joints and connections c)-replacing faulty equipment d)-all of the given options

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.
