1. The problem statement, all variables and given/known data Water flows through a venturi meter, with an inlet diameter of 25cm and a throat diameter of 15cm. The pressure difference is measured using a manometer, which displaces the mercury by 12mm on the throat side. 2. Relevant equations Bernoulli's Mass continuity P=rho.g.h 3. The attempt at a solution Is this correct? I have no answers available as its from a past paper. My exam is tommorow and I would just like to clarify that the method I have used to find the pressure difference is correct. Thanks.
