Critical velocity is that velocity of liquid flow up to which its flow is
streamlined and above which its flow becomes turbulent.
Hence the critical velocity of a liquid is that velocity of flow above which the flow ceases to be streamlined.
\({v_c} = K\frac{\eta }{{\rho r}}\)
Where η is the coefficient of viscosity, ρ is the density of the liquid and r is the radius of the tube. K is constant, known as the Reynolds number.Last updated on May 28, 2025
