1)
State the Pascal's law of pressure at a point in a fluid.
2)
Most swimmers find the pressure at a depth of about 10 ft painful to
ears. What is the gauge pressure at this depth?
3)
How far below surface of water must one dive for the pressure to
increase by one atmosphere?
4)
At what depth below the free surface of oil having a density of 600
kg/m

will the pressure be equal to 1 bar?
5)
What would the pressure in kN/m

be if the equivalent head is
measured as 550 mm of :

Mercury , S.G = 13.6
b.
Water

6)
What will be (a) the gauge pressure (b) the absolute pressure of water
at a depth of 12 m below the free surface?

An open tank contains oil of S.G 0.75 on top of water. If the depth of
oil is 2 m and the depth of water 3 m, calculate the gauge and
absolute pressures at the bottom of the tank when the atmospheric
