# Hydrostatics Problem Finding h

## Homework Statement

So this is a five part problem. I have already done the first 4 parts that involved the mess of different liquids to the left in the diagram.

I am only concerned with finding h now, which I believe does not even require me to look at the left hand side of the diagram.

I should be able to find it using only H1, H2, (SG)Hg, gammaL and patm

I also labeled a point a because I believe it will be of use to me. ## Homework Equations

The hydrostatic relation $p=p_o+\rho g y=p_o+\gamma y$

Can someone give me a hint? I have done tons of these before, but I am stumped for some reason on this one What is confusing is that i am given "heights" and not "depths." Not sure why that is effing me up so badly.

Hg level in left tube = H1 - h
Hg level in right tube = H2
Find the excess mercury level in the right hand tube.
Excess pressure due to this level must be balanced by the excess pressure due to h level of liquid of density of γL.

H2-(H1-h)γHg=hγL

That look about right rl.bhat ?

H2-(H1-h)γHg=hγL

That look about right rl.bhat ?
It should be [H2-(H1-h)]γHg=hγL
