The performance of a hydraulic structure during a flood has been investigated in a 1/25 model based on Froude law of similarity. A flood wave passing through the model in 2 hrs. Corresponds to a prototype period of:

Q. A river reach of 2.0 km long with maximum flood discharge of 10000 $m^3/s$ is to be physically modeled in the laboratory where maximum available discharge is $0.20m^3/s$. For a geometrically similar model based on equality of Froude number, the length of the river reach (m) in the model is

Q. The height of a hydraulic jump in the stilling pool of 1:25 scale model was observed to be 10 cm. The corresponding prototype height of the jump is

Q. In $\frac{1}{{100}^{th}}$ model of a harbour, what length of the time should correspond to prototype tidal time period of 12.4 hrs?

Q. In a flow condition both viscous and gravity forces dominate and both the Froude number and the Reynolds number are the same in model and prototype and the raio of kinematic viscosity of model to that of the prototype is 0.0894. What is the model scale?

Q. A ships model of scale 1: 100 had a wave resistance of 1 N at its design speed. The corresponding wave resistance (in N) in prototype will be -
