Thrust acting on the bottom surface of a tank having dimensions 4 m × 4 m × 4 m when fully filled with water of density 103 kg m-3 is
6.27 × 105 N
6.27 × 106 Pa
6.27 × 104 N
62.7 × 105 N
Thrust, F = mg = volume × density × g = 64 × 103 × 9.8 = 6.27 × 105 N
The pressure exerted by water (density = 103 kg/m3) on the bottom surface (2m × 4m) of tank having dimensions 2m × 4m × 2m is
A rectangular tank has dimensions 4 m × 3 m × 3 m. The amount of water it will contain when it is two-third filled is___
