A dam 75 ft wide, with a nominal flow rate of 260 ft3/s, is to be studied with a scale model 3 ft wide, using Froude scaling as the most important similarity parameter. (a) What is the expected flow rate for the model? (b) What is the danger of only using Froude scaling for this test? Show what other dimensionless parameters could be relevant when scaling this problem. (c) Derive a formula for a force on the model as compared to a corresponding force on the prototype.

An insulated rigid tank contains 5 kg of a saturated liquid-vapor mixture of water at a. Initially, three-quarters of the mass is in the liquid phase. An electric resistor placed in the tank is connected to a 110-V source, and a current of 8 A flows through the resistor when the switch is turned on. (a) Determine how much time it will take to vaporize all the water in the tank, and (b) show the process on a T-v diagram with respect to the saturation lines.
