Example 1:
Two pipes on the same elevation convey water and oil of specific gravity 0.88 respectively. They are connected by
a U-tube manometer with the manometric liquid having a specific gravity of 1.25. If the manometric liquid in the
limb connecting the water pipe is 2 m higher than the other find the pressure difference in two pipes.

Given data:
Height difference = 2 m
Specific gravity of oil s = 0.88
Specific gravity of manometric liquid s = 1.25
Fig. Ex1
Equating pressure head at section (A-A)
Substituing h = 5 m and density of water 998.2 kg/m* we have P A -P B = 10791
Answer:- 10791 Pa
