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.

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
