- 32. The incremental cost characteristics of two generators delivering a load of 200 MW are as follows: dF = 2.0 + 0.01 P, dP, dP dF, -= 1.6 + 0.02 P, For economic operation the generators P, and P, should be (a) 120 MW and 80 MW (b) 81 MW and 120 MW (c) 120 MW and 120 MW (d) 80 MW and 80 MWarrow_forwardTwo cities A and B are connected by a 200km long train line. A train leaves A for B at 20 km / h at the same time as another train leaves B for A at 5 km / h. In the samemoment a fly leaves from A to B following the train line. The fly flies at 40 km / h until it collides with train B. At that moment it returns instantly and follows the train line until it collides with train A. At that moment it returns instantly and follows the line of the train. train until it collides with train B. The fly continues this process, traveling ever smaller distances until the two trains meet. (It is an ideal problem and the fly does not get squashed by the trains).What is the total distance traveled by the fly?arrow_forwardFrom the plotted power curve determine the following: a) Peak power = ___________W b) Peak power occurs at ___________o c) Does the instantaneous power ever go negative? ___________ d) Are all of the power curve peaks of equal magnitude? ___________ e) Is the enclosed area under the positive power curve the same as the enclosed area under the negative power curve? ___________ f) The average (apparent) power for one complete cycle (360°) in voltamperes = ___________VA. g) The average (real) power for one complete cycle(360°) in watts = ___________VA.arrow_forward
