Question: A venturi meter, shown in Fig P3.165, is a carefully designed constriction whose pressure difference is a measure of the flow rate in a pipe.

A venturi meter, shown in Fig P3.165, is a carefully designed constriction whose pressure difference is a measure of the flow rate in a pipe. Using Bernoulli€™s equation for steady incompressible flow with no losses, show that the flow rate Q is related to the manometer reading h by
