Chapter 5, Problem 46EP
Water flows through a horizontal pipe at a rate of 2.4 gal/s. The pipe consists of two sections of diameters 4 in and 2 in with a smooth reducing section. The pressure difference between the two pipe sections is measured by a mercury manometer. Neglecting frictional effects, determine the differential height of mercury between the two pipe sections.

A horizontal Venturimeter with inlet and throat diameters 300 mm and 150 mm respectively is used to measure the flow of water. The reading of differential manometer connected to the inlet and the throat is 20 cm of mercury. Determine the rate of flow. Take Cd = 0.98.
In a horizontal pipe water flows at a rate of 9.1 L/s. Here, the pipe has two sections, one with a diameter of 10.16 cm and the other with a diameter of 5.08 cm, with a gradual smooth reducing section. In this case, a mercury manometer is used to measure the pressure difference. If friction is negligible how would I find the differential height of mercury between the two sections? If the manometer on the 5.08cm pipe section was replaced with a pitot tube how would the reading change?
any help would be deeply appreciated
