Answer 1

Given:

An open tank contains 1 metre deep water. Above it , there is 50 cm depth of oil of specific gravity 0.8.

To find:

Total pressure at the bottom of the tank.

Calculation:

Total pressure at the bottom of the tank can be calculated by algebraic summation of individual pressure exerted by the liquids.

$P = ( \rho1)g(h1) + ( \rho2)g(h2)$

$= > P = (800 \times 10 \times 0.5) + (1000 \times 10 \times 1)$

$= > P = 4000 + 10000$

$= > P = 14000 \: Pa$

$= > P = 14 \: \: kPa$

So net pressure at the bottom of the tank is equal to 14 kPa.
