Question

Brine (specific gravity 1.20) is flowing through a standard 80-mm pipe at a maximum rate of 0.9 m³/min. In order to measure the rate of flow, a sharp-edged orifice, connected to a simple U-manometer is to be installed. The maximum reading of the manometer is to be 400 mm Hg. What size orifice should be installed? Repeat, assuming a venturi meter is used instead of an orifice.
