A servo-mechanism is to make use of a venturi contraction in a horizontal 350

A servo-mechanism is to make use of a venturi contraction in a horizontal 350 mm diameter pipe carrying a liquid of relative density 0.95. The upper end of a vertical cylinder 100 mm diameter is connected by a pipe to the throat of the venturi and the lower end of the cylinder is connected to the inlet. A piston in the cylinder is to be lifted when the flow rate through the venturi exceeds 0.15 m3 ·s−1. The piston rod is 20 mm diameter and passes through both ends of the cylinder. Neglecting friction, calculate the required diameter of the venturi throat if the gross effective load on the piston rod is 180 N.
