Question

What is the pressure at the bottom of a tank 1-m deep? Take the density of water to be 1000-kg/m^3, and gravitational acceleration to be 9.8-m/s^2. Enter your answer in N/m^2.

Answer 1

To solve this problem we will use the concepts related to hydrostatic pressure. Which determines the pressure of a body at a given depth of a liquid.

Mathematically this can be described as

$P= \rho gh$

Here

$\rho$ = Density

g = Gravity

h = Height (Depth)

If we replace the values given in the equation we will have to

$P = 1000 (9.8)(1)$

$P = 9800 Pa$

Therefore the pressure at the bottom will be 9.8kPa
