Question

The pressure in a water pipe on the ground floor is 100000 pa. Calculate the pressure at first floor. Of jeight =3 m.

Answer 1

Answer:

70000 Pa.

Explanation:

Taking g = 10m/s^2

We know, pressure = height * density of water * g

so, 100000 = h * 1000 * 10

so, h = 10 m

now, first floor is at 3 m, therefore height at first floor is 7 m.

now, pressure = 7 * 1000 * 10

= 70000 Pa.

Answer 2

Answer:

70000 Pascal
