Question

There is a hole in the bottom of a tank having water. If total pressure at the bottom is 3 atm 1 atm = 10 5 N m - 2 , then the velocity of water flowing from the hole is, 400 m s - 1, 600 m s - 1, 60 m s - 1, None of these

MARKS App · Accepted Answer

Pressure at the bottom of the tank is given by P = hρg =3×10 5 N m - 2 and velocity of water is given by v = 2 gh . ∴ v = 2 P ρ = 2 × 3 × 1 0 5 1 0 3 = 6 0 0 m / s
