Water flows over Victoria Falls, which is 128 m high, at an average rate of 1.39 × 106 kg/s. The acceleration of gravity is 9.81 m/s 2 . If half the potential energy of this water were converted into electric energy, how much power would be produced by these falls? Answer in units of MW.
Approximately 2.1 x 105 kg of water falls 14 m over a waterfall each second. (a) What is the decrease in the gravitational potential energy of the water-Earth system each second? (b) If all this energy could be converted to electrical energy (it cannot be), at what rate would electrical energy be supplied? (The mass of 1 m3 of water is 1000 kg.) (c) If the electrical energy were sold at 1.7 cent/kW·h, what would be the yearly income in...
A 100ft waterfall has a flow rate of 1000 kg/s is to be used to generate power by striking fins located on the perimeter of a wheel. Determine the power generation potential of this stream of water.
Approximately 1.0 x 106 kg of water falls 45 m over a waterfall each second. (a) What is the decrease in the gravitational potential energy of the water-Earth system each second? (b) If all this energy could be converted to electrical energy (it cannot be), at what rate would electrical energy be supplied? (The mass of 1 m3 of water is 1000 kg.) (c) If the electrical energy were sold at 3.3 cent/kW·h, what would be the yearly income in...
Water going over a fall splashes on rocks 20 m below. If 20 kg of water flows over the fall per second, how much force do the rocks exert on the falling water?

A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.65 m high, and from there the water falls into a pool (see figure). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? YesNo (b) To sell her plan to the city council, the architect wants to build a model to...
