Show complete solution with diagram:
A 3.81-cm diameter venturi meter is installed in a pipe with an internal diameter of 10.23 cm. A 127 cm manometer filled with mercury is used to measure the pressure difference across the venturi meter. If the manometer reads 101.6 cm when 15 °C water is flowing through the pipe, what is the flow rate of water (m3/min)? Assume that the venturi meter coefficient of discharge equals 0.98.
A venturi meter with a throat diameter of 100 mm is fitted in a vertical pipeline of 200 mm diameter with oil of specific gravity 0.88 flowing upwards. Two pressure gauges are fitted at tapping points, one at the throat and the other one in the inlet pipe 320 mm below the throat. The difference between the gage pressure readings is 28 kPa. (a) Determine the flow in m^3/s neglecting head losses. (b)Working from Bernoulli's equation, determine the difference in level (in millimeters) between the two limbs of a mercury manometer if it is connected to the tapping points and the connecting pipes are filled with the same oil.
