water is pumped from a borehole whose elevation is 564m to a tank in a school compound at an elevation of 2096m. the radius of the pipe at the inlet is 4cm while pressure is 400 kpa. at the exit the radius of the pipe is 2cm. calculate the pressure at the exit.(inlet = 2 m/s)

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.
