Question

A building is 512 m high. What must be the minimum water pressure in a pipe at ground level in order to get water up to a restaurant on the top floor? [3] (Density of water = 1000 kgm-3)

Answer 1

The minimum pressure required to get water up to a restaurant on the top floor is 5.0176 x 10⁶ N/m²

Step-by-step explanation:

Given;

height of the building, h = 512 m

density of water, ρ = 1000 kg/m³

The minimum pressure required to get water up to a restaurant on the top floor is calculated as follows;

P = ρgh

where;

P is the required minimum pressure

g is acceleration due to gravity = 9.8 m/s²

P = 1000 x 9.8 x 512

P = 5.0176 x 10⁶ N/m²

Therefore, the minimum pressure required to get water up to a restaurant on the top floor is 5.0176 x 10⁶ N/m²
