Water discharges over a spillway at a rate of 10,000 cfs over a rectangular spillway 40 feet wide into stilling basin. The lake level upstream from the spillway is at an elevation of 200 feet above the datum. The subcritical water level in the channel downstream from the stilling basin is at an elevation of 100 feet above the datum. assume no energy loss over the spillway, determine the invert of the stilling basin required to form a hydraulic jump in the channel.
A coal-fired power plant produces a net electrical output of 500 MW. The composition of the coal burned is C= 72 %, H= 6 %, S= 3.5 %, O= 6 %, N= 1 %, and ash= 12 % by weight. It's heating value (HV) is 30200 kJ/kg. The net thermal efficiency is 36..
