1.3 A factory near a water fall where the usable head for power generation is 25m. The river flow throughout the year is 10m³/sec minimum. The site is developed as a run-of-river type of generating plant without storage, to supply this factory. Assuming the overall efficiency of the plant to be 80% and 1m³ weighs 1000kg. Determine: 1.3.1 The gross plant capacity. [4] 1.3.2 The firm capacity of the plant 1.3.3 The yearly gross output [2] 1.4 In order to operate the generating units near their point of maximum efficiency, the number and size of the units are selected in such a way that they correctly fit the load saturation curve. Mention four important points that must be considered in the selection of the generating units. [24]
