उत्तर
Pressure of water at ground floor = P, = 160000 Pa
Pressure of water at the fifth floor = P2 =?
Height of fifth floor = h = 15 m
Density of water = ρ = 1000 kgm−3
Difference in pressure of water at ground and fifth floor
= P1 – P2
Pressure of water due to height (h) = hρg
= P1 – P2 = hρg
160000 – P2= 15 × 1000 × 10
P2= 160000 – 150000
P2 = 10000 Pa
