JEE Main 2020 — Mechanical Properties of Fluids Question with Solution

JEE Main 2020 (06 Sep Shift 2)

Question

A fluid is flowing through a horizontal pipe of varying cross-section, with v ms−1 at a point where the pressure is P Pascal. At another point where pressure P2 Pascal its speed is V ms-1. If the density of the fluid is ρ kg−m-3 and the flow is streamline, then V is equal to

Correct answer
DPρ+υ2

Step-by-step explanation

P+12ρv2=P2+12ρV2

P2+12ρv2=12ρV2 ;

V=v2+Pρ
