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= 10 ms-2.
Answer:-Apply (p1-p2)=h×10^3kg/m^3×10ms^-2=6m

Answer 1

hey

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

3×2 = 6

hope it helps you
