A dam spillway is tested with a 1/30th scale model, matching the Froude number. The flow over the dam has an average velocity of 0.6 m/s and a volume flow rate of 0.08 m^3/s.

a. What will be the velocity and flow rate for the model?

b. If a force is measured on the model as 1.5 N, what is the corresponding force on the real dam?
