A Venturi is to be installed to measure the flow of water. The mass flow rate of water used in the process is not expected to exceed 5 kg/s. The Venturi is to be located in a straight section of horizontal pipe with a 50 mm inside diameter and is to be connected to a mercury-filled differential manometer. If the maximum allowable pressure differential is 70 kNm$^{-2}$, determine the throat area required for the flowmeter. The coefficient of discharge may be assumed to be 0.96. Density of water is 1,000 kg/m$^3$
