1.The flowrate through an open channel with a slope of 2 % is calculated using Manning's equation at 100 cubic feet per second. If the slope of the channel is doubled to 4% (with all other variable remaining the same) what is the new flowrate?
2.A model is to be produced for a prototype with reynolds number similitude. The prototype and model will both be in air, if the prototype has a velocity of 500 ft/s and a diameter of 30 ft, what should the velocity for the model be if the model diameter is 2 ft?
