## Homework Statement

Derive an equation for the pressure difference p – B in terms of ρM, ρ, L, θ, a, A

and the acceleration due to gravity g

## Homework Equations

(LHS p')= B+(ρm)g(Lsinθ+h+Δ) = (RHS p') P+ρg(Lsinθ+H)

Δ=delta = La/A

a= area of tube, A= area of reservoir

h= ρH/ρm

## The Attempt at a Solution

P-B= ρmg(Lsinθ+(ρH/ρm)+(La/A)) - ρg(Lsinθ+H)

= (ρm-ρ)g(Lsinθ)+ (Lsinθ+(ρ/ρm)+(La/A)

I was just wondering if this is the correct formula for P-B
