1. Head is less than 5 times the depth is called large.

2. Head is more than 5 times the depth is called a small orifice.

If the head of the liquid from the centre of the orifice is more than five times the depth of the orifice, the orifice is called small orifice. And if the head of the liquid is less than five times the depth of orifice, it is known as a large orifice.

H<2D FOR big orifice.
H>2D SMALL orifice.

H<5d, for large orifice. d=depth of orifice(h2-h1).

So ans is h2-h1> H/5. Here not given.

I agree @Roy.

According to me, C is correct.

Roy said:   6 years ago
Head of the liquid (H2-H1) <5 D, where D is the depth of orifice.
