Question

The pressure of water on ground floor, in a water pipe is 170000 Pa, whereas pressure on the fourth floor is 45000 Pa. Calculate height of the fourth floor. [ Take g = 10 m/s2 ]. *​

Answer 1

Answer:

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.
