JEE Main 2016 — Mechanical Properties of Fluids Question with Solution

JEE Main 2016 (09 Apr Online)

Question


Consider a water jar of radius R that has water filled up to height H and is kept on a stand of height h (see figure). Through a hole of radius r r<<R at its bottom, the water leaks out and the stream of water coming down towards the ground has a shape like a funnel as shown in the figure. If the radius of the cross-section of water stream when it hits the ground is x. Then:

Correct answer
Ax=rHH+h14

Step-by-step explanation

Using equation of continuity

π r 2 2 gH = π x 2 2 g H + h

x = r H H + h 1 4
