Derive an expression for small ow rates over a spillway, in the form of function using dimensionless quantities. Use dimensional analysis with following parameters : height of spillway P, head on the spillway H, viscosity of liquid , density of liquid , surface tension , and acceleration due to gravity g.

A55-kg pilot flies a jet trainer in a half vertical loop of 1200-m radius so that the speed of the trainer decreases at a constant rate. knowing that the plane has a speed of 550 km/h at point a, and the pilot experiences weightlessness at point c (i.e., the normal force from the seat bottom is zero), determine (a) the deceleration of the plane, (b) the force exerted on her by the seat of the trainer when the trainer is at point b.
