A fluid (μ/ρ) = 0.01 cm2/sec is moving at critical flow condition (NRe = 2100) through a pipe of dia 3 cms. Velocity of flow is _______________ cm/sec?
Correct answer: A
Explanation
The flow rate (Q) is calculated using the given fluid property and Reynolds number. Then, velocity (V) is found by dividing Q by the cross-sectional area.
