Properties of Matter question

2020 · 6 Sep · Shift 2 · Q39

JEE MainPhysicsProperties of MatterMCQ+4 / −1
A fluid is flowing through a horizontal pipe of varying cross-section, with speed v ms–1 at a point where the pressure is P pascal. At another point where pressure is P2{P \over 2}2P​ Pascal its speed is V ms–1. If the density of the fluid is ρ\rhoρ kg m–3 and the flow is streamline, then V is equal to :
  1. A
    P2ρ+v2\sqrt {{P \over {2\rho }} + {v^2}}2ρP​+v2​
  2. B
    Pρ+v2\sqrt {{P \over \rho } + {v^2}}ρP​+v2​
  3. C
    2Pρ+v2\sqrt {{{2P} \over \rho } + {v^2}}ρ2P​+v2​
  4. D
    Pρ+v\sqrt {{P \over \rho } + {v}}ρP​+v​
