A horizontal pipe has a cross sectional area of 40.0 cm^2 at the wider portions and 10.0 cm^2 at the constriction. Water is flowing in the pipe, and the discharge from the pipe is 6.00*10^-3 m^3/s(6.00 L/s). Find (a) the flow speeds at the wide and the narrow portions; (b) the pressure difference between those portions; (c) the difference in height between the mercury columns and the U-shaped tube.
