Problem 1: A Venturi meter (shown in the Figure) is used for measuring flow of water along a pipe. The diameter of the Venturi throat is two fifths the diameter of the pipe. The inlet and throat are connected by water filled tubes to a mercury U-tube manometer. The velocity of flow along the pipe is found to be 2 5 H¹/2 m/s, where H is the manometer reading in metres of mercury. Determine the loss of head between inlet and throat of the Venturi when H is 0.49m. (Relative density of mercury is 13.6). Z1 H 22

Using Bernoulli's in the form: P1+pgh1+1/2pv1^2=P2+pgh2+1/2pv2^2

Problem 1: A Venturi meter (shown in the Figure) is used for
measuring flow of water along a pipe. The diameter of the
Venturi throat is two fifths the diameter of the pipe. The inlet
and throat are connected by water filled tubes to a mercury
U-tube manometer. The velocity of flow along the pipe is
found to be 2 5 H¹/2 m/s, where H is the manometer reading
in metres of mercury. Determine the loss of head between
inlet and throat of the Venturi when H is 0.49m. (Relative
density of mercury is 13.6).
