A20 m high filled water tank develops a 0.50 cm hole in the vertical wall near the base. with what speed does the water shoot out of the hole? a) 30 m/s
b)15 m/s
c) 25m/s
d) 20 m/s

The speed of the water shoot out of the hole is 20 m/s.

(d) is correct option.

Explanation:

Given that,

Height = 20 m

We need to calculate the velocity

Using formula Bernoulli equation

Where,

v₁= initial velocity

v₂=final velocity

h₁=total height

h₂=height of the hole from the base

Put the value into the formula

Hence, The speed of the water shoot out of the hole is 20 m/s.

v=ir = 3x15 =45 v
