Question

A pressure in a water pipe on the ground floor is 12000Pa whereas on the second floor, it is 2000Pa. find the height of the second floor. (take g = 10m/s2 )​

Answer 1

Explanation:-

Difference in pressure of water at ground floor and third floor

=(120000−300000)=900000Pa

Density of water =1000kgm

−3

Let 'h' be the height third floor.

P=hdg

h=

dg

p

​

=

1000×10

90000

​

=9m.
