A power plant serves a factory having two 22 kw motors and ten 3.7 kw motors. Assume the
efficiency of motors 80%, of transmission line 95%, of generator 92%. (a) What should the rated
capacity of the generator be if it is assumed that all motors might be delivering their rated power
simultaneously? (b) What should the rated capacity of the engine be?

    CODE 102_8 Welding Many welding processes require the application of heat and/or pressure to produce a suitable bond between the two parts being joined. There are a number of conventional and commercially practiced welding processes, which possess limitations in relation to material type and thickness, and in addition, the cost analysis may not allow for a process to be used on a specific application. The selection of suitable welding consumable (electrode or wire) is also an important factor in producing...
