FLUID MECHANICS

EXERCISE 5

1. In the figure below, fluid P is water and fluid Q is mercury (specific gravity=13.6). If the

2
pressure difference between A and B is 35 kN/m , a = 1 m and b = 30 cm, calculate the
difference of level h. Ans. 30.7 cm

2. According to the figure in question no. 1, fluid P is oil (specific gravity = 0.85) and fluid

Q is water. If a = 120 cm, b = 60 cm and h = 45 cm, compute the difference in

2
pressure in kN/m between A and B? Ans. -4.34 kN/m 2

3. In the figure below, fluid Q is water and fluid P is oil (specific gravity = 0.9). If h = 69 cm
2
and z = 23 cm, what is the difference in pressure in kN/m between A and B?

Ans. 2.933 kN/m 2
