A Venturi meter with a 15 cm LD. at inlet and 10 cm I.D. at throat is laid with its axis horizontal and is used for measuring the flow of oil of sp.gr. = 0.9. The oil-mercurry differential manometer shows a gauge difference of 20 cm. If Ca = 0.98, calculate the discharge of oil. Ans. Q = 0.06393 m/s P.7.5 A horizontal Venturi meter (160mm x 80mm) used to measure the flow of oil of sp.gr. = 0.8. Determine the deflection of oil-mercury gauge, if discharge of oil is 50 lit/s. Ans. R = 29.6 cm Hg P.7.6 A Venturi meter has an area ratio (9:1), the larger diameter being 30 cm. During the flow the recorded pressure head in larger section is 6.5 m and that at throst 4.25 m. If Ca = 0.99, compute the discharge through the meter. Ans. Q = 0.052 m/s P.7.7 A Venturi meter is fitted to 15 cm diameter pipeline conveying water inclined at 60° to the horizontal. The throat diameter is 5 cm and it is placed higher than the inlet side. The difference of pressure between the throat and the inlet which are 0.9 m apart is equivalent to 7.5 cm of mercury. Calculate the discharge if Ca = 0.98. Ans.
