Prove that the velocity of efflux through an orifice is equal to the velocity attained by a freely falling body from the surface of the liquid to the orifice. Also find the horizontal range in terms of height. ( 5marks)
Dear Student,
H = Height of container
h = Height from the surface of the container to the orifice made
Let atmospheric pressure be P , density of liquid in tank be and velocity of liquid at efflux be v
Applying Bernoulli's equation at the surface of container and at the orifice we get
Thus the velocity of efflux is
