Calculate the water pressure in the pipes at the bottom of a high-rise building that is fed by reservoir 30 m above the roof top. and explain

P₀ = atmospheric pressure = 101325 Pa

P = pressure at the pipes

h = height of reservoir = 30 m

ρ = density of water = 1000 kg/m³

g = acceleration due gravity = 9.8 m/s²

pressure at the pipes is given as

P = P₀ + ρgh

P = 101325 + (1000) (9.8) (30)

P = 3.95 x 10⁵ Pa

hence the water pressure in the pipes at the bottom is given as

3.95 x 10⁵ Pa

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.
