Question

Determine the absolute pressure on the bottom of a swimming pool 27.0 m by 8.9 m whose uniform depth is 1.8 m . Express your answer using two significant figures.

Answer 1

`P=17658Pa`

Step-by-step explanation:

From the question we are told that:

Dimension

`L*B=27.0*8.9`

Depth
`d=1.8m`

Generally the equation for Volume of water is mathematically given by

`V=L*B*D`

`V=27.0*8.9*1.8`

`V=432.54m^3`

Therefore

Force at the bottom of the Pool

`F=\rho Vg`

Where

`\rho \ density\ of \ water(1000kg/m^3)`

`F=1000*432.54m^3*9.81`

`F=4.2*10^(6)N`

Generally the equation for Pressure at the bottom is mathematically given by

`P=(Forece )/(Area)`

`P=(4.2*10^(6)N)/(27.0*8.9)`

`P=17658Pa`
