Question

(2) Oil with S.G.=0.85 flows along a pipe and passes through a Venturi meter. Piezometer tubes are attached upstream of the contraction and in the throat of the contraction. The

upstream and throat pipe diameters are D1=0.08 m and D2=0.04 m respectively. The oil elevation in the piezometers differs by H=0.4 m. a. Calculate the volume flow rate in the Venturi meter. b.Calculate the mass flow rate in the venture meter C.How would your answer to (a) change if water was flowing but D1, D2, and H were unchanged?
