Question

he surface of the water in a water tank on the top of a house is 4 m above the tap level. Find the pressure of water at the tap when the tap is closed. Is it necessary to specify that the tap is closed? Take g = 10 m/s².

Answer 1

Given conditions,

density (ρ) =1000 kg/m³

acceleration due to the gravity (g) =10 m/s²

height (h) =4 m

Using the Formula,

     P = ρgh  

∴ P = 1000 × 10 × 4 N/m²

 P = 40000 N/m².

 Hence, the pressure is 40,000 N/m².

Hope it helps.

Answer 2

Hey there!

Given,
Density of Water = d = 1000 kg/ m^3
Height from tap level = h = 4 m
Acceleration due to gravity = g = 10 m/s^2

We know,
P = hdg
P = 4 × 1000 × 10
P = 4 × 10^4 Pa
