Two three-phase generators supply a three-phase load through separate three-phase lines. the load absorbs 30 kw at 0.8 power factor lagging. the line impedance is (1.4 + j1.6) ω per phase between generator g1 and the load, and (0.8+j1) ohm between generator g2 and the load. if generator g1 supplies 15 kw at 0.8 power factor lagging with a terminal voltage of 460 v line-to-line, determine

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.

How to increase the thermal officiency of an ideal simple rankino cycle? among these methods, which one is the best and why?

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
