Water flows from a beaker into a 4-mm-diameter tube with an average velocity of 0.45 m/s.
Classify the flow as laminar or turbulent if the water temperature is 10∘C (so its kinematic viscosity is ν=1.31(10−6)m2/s) and if it is 30∘C (so its kinematic viscosity is ν=0.804(10−6)m2/s). Critical Reynolds number is 2300.
A. Turbulent for 10∘C water and laminar for 30∘C water.
B. Turbulent for both 10∘C and 30∘C water.
C. Laminar for both 10∘C and 30∘C water.
D. Laminar for 10∘C water and turbulent for 30∘C water.
