Water pressure at bottom of the tank (P) =ρgh
Where ρ = Density of water,
g = Acceleration due to gravity,
h = Height of the water in the tank.
Total water force at bottom of the tank (F) = Water pressures at bottom of the tank (P) × Area of the tank bottom (A)
Total water force at bottom of the tank (F) = ρghA
Calculation:
Given data:
Height of tank (h) = 3 m
Width of the tank (b) = 2 m and length of tank = 2 m
Total water force at bottom of the tank (F) =?
g = 9.81 m/s
ρ = 1000 kg/m3
Area of tank bottom (A) = 2 × 2 = 4 m2
Total water force at bottom of the tank (F) = 1000 × 9.81 × 3 × 4 = 117720 N
Total water force at bottom of the tank (F) = 117.720 kN
