Explanation:
First calculate v = (1 ml/min) (1 min/60sec) (1/(0.0375 x 0.0375 x 3.14)) = 3.77 cm/s. Re = 28. Flow is laminar. One may use a Moody plot for laminar flow, but the corresponding equation for Re, as given on the Engineers Edge website linked in Unit 4, is preferable. In the present case Δ P= (64/28) x (L/D) x( ρ/2) x v2=2.1kPa.
