Bernoulli's Equation: Water is flowing through the pipe shown in the figure below at a flow rate

The horizontal pipe shown has a cross-sectional area of 40 cm^2 at the wider
portions and 10 cm^2 at the constriction. Water is flowing in the pipe, and the
discharge from the pipe is 6x10-3 m3/s. Find (a) the flow speeds at the wide and
narrow portions; (b) the pressure difference between these portions; (c) the
difference in height between the mercury columns in the U-shaped tube
