**1. Homework Statement**

A 4 inch to 1 inch diameter venturi meter is used to measure water flow and it

has a mercury manometer deflection of 1 inch. What is the discharge

through the four inch diameter pipe?

**2. Homework Equations**

Bernoulli Equation, manometer formula

**3. The Attempt at a Solution**

Thus far my attempt at a solution is using the Reynolds Transport Theorem. I know that for a steady flow process that there will be no change in volume for the control volume. Thus that term will be zero. So now I am left with

∫ρV*dA

I have two diameters given and I know that it is a in-compressible fluid. So my flow in must equal my flow out. I am confused however upon the given information regarding the mercury deflection. Am I to use that deflection to give myself a pressure? Or is that a piece of information that is nonessential in approaching this problem?
