A 1:50 model of a spillway is to be tested in the laboratory

Q. A 1:50 model of a spillway is to be tested in the laboratory. The discharge in the prototype spillway is 1000 m3/s. The corresponding discharge (in m3/s, up to two decimal places) to be maintained in the model, neglecting variation in acceleration due to gravity, is                                         

Ans: 0.05 – 0.06

Sol:

Given: Discharge in prototype, QP = 1000 m3/sec, Lr = 50

Froude number of models = Froude number of prototypes

We will be happy to hear your thoughts
