Question

Water flows through a venturi meter which contracts from D = 300 mm to

d = 150 mm at the rate of 0.0037 m3

/s and the differential gauge has a

deflection, h of 1 m, as shown in the figure below. Specific gravity of the

gauge liquid is 1.25. Determine the coefficient of discharge of the meter.

Answer 1

Answer

Quantity of fluid is

$Q=\frac{c_d A_1A_2\sqrt{2gh}}{\sqrt{A_1^2-A_2^2}}$

Putting all values

coefficient of discharge of the meter.

$c_d=0.92$
