The Froude law is to be used to study the operation of tide gates on a large river. If the closure time for the prototype gates is 20 min, determine the model closure time if the length ratio is (1) 1:50 and (2) 1:100.
Determine the horsepower required to close one of the tide gates in Prob. 9-12(1) if the model power requirement is 0.25 ft-lb/s.
