fluid Q1: A venture meter is fitted in a pipe of 30 cm diameter inclined at 40° to the horizontal to measure the flow rate of petrol having a specific gravity of 0.8. The ratio of areas of main pipe and throat is 5 and the throat is at 1 m from the inlet along its length. The difference in manometer head is 40 mm of mercury. Assuming the coefficient of discharge as 0.96. Calculate the discharge through the venture...
(c) Fuel oil, with a density of 870 kg m-, is pumped through a horizontal pipe, as shown in Figure Q2.2. The pipe is 100 mm in diameter and contains an orifice plate with a throat diameter of 40 mm. The pressure drop across the orifice is measured on a U-tube manometer, containing mercury with a specific gravity 13.6. The difference in levels of the columns is measured as 45 mm. The coefficient of discharge for the orifice plate Ca...
