Problem 7
A double inverted U-tube manometer containing oil (SG = 0.8), mercury
(SG = 13.6) and water is used to measure large pressure difference
between gas in pipe B and gasoline in pipe A as shown in figure.
Knowing that h₁ = 60 cm, h₂ = 87 cm, h3 = 35 cm, and h4 = 24 cm,
determine the presure difference between A and B. Neglect the gas
density and use Ywater = 9810 N/m³ for water.

Expert Solution

Step 1: Determine the pressure difference between point A and B.

Given:

The specific gravity of oil is $S_{G} = 0.8$ .

The specific gravity of oil is $S_{o} = 13.6$ .

The specific weight of Water $γ_{w} = 9810 N / m^{3}$ , $h_{1} = 60 cm$ , $h_{2} = 87 cm$ and $h_{3} = 35 cm$ .

Formula used:

The expression for increase in pressure at depth $z$ is given by,

$P = ρ g z$

Here, $P$ is Pressure, $ρ$ is density, $g$ is acceleration due to gravity, $z$ is vertical distance.

The expression for density of fluid is given as,

$ρ_{f} = (S G) ρ_{w}$
