Question

The pressure in water pipe at the ground level of a building is 1.5×10^5pa, whereas the pressure on the second floor is 0.9×10^5pa. calculate the height of the second floor ... take g=10m/s

Answer 1

Let H1 be the distance between tank and ground floor.

Let H2 be the distance between tank and 1st floor.

H1-H2=h (Distance between the 2 floors)

d=density of water=1000kg/m^3

dgH1 = 4*10^4

dgH2 = 1*10^4

dg(H1-H2)=3*10^4

dgh=3*10^4

dh=3*10^3

h = 3

hope it helps you

Answer 2

Answer:

The answer is 6m

Explanation:

From the formula of h=P/pg

p=density of water

P=pressure

g=gravity

firstly subtract both the pressure which is given then apply the above formula
