Question

The pressure at a water top at the base of a building is 7.9*10^4kgwt/m^2 and at its top is 5.4*10^4kgwt/m^2. Find the height of the building

Answer 1

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

5.4×10^4 + dh = 7.9×10^4

54000 + 1000h = 79000

1000h = 79000 - 54000

1000h = 25000

h = 25 m
