The flow rate over niagara falls is 84,760 cfs (cubic feet per second), and the drop from top to bottom is 167 feet. if this flow were harnessed to generate electricity, at what rate would power be produced? assume 100% conversion of potential energy into electrical energy. how does this compare with the power generated by the three gorges dam?
