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...
Thats what I have been given on my question sheet, also they just give numerical answers and on the sheet it says the correct answer is 3800K that is why i put it up to check??
