With the following physical characteristics : rho = 988 kg / m3, μ = 5?
With the following physical characteristics : rho = 988 kg / m3, μ = 5. 47 × 10 - 4 p. S, v = 0. 553 × 10 - 6 m2 / s. The pipe has a diameter of 450 mm and the flow rate is 630 l / s. In a 60 m section a piezometric pressure drop of 6. 2 m is measured, and an overall loss coefficient of less than 2. 4. 7. 1. calculate the absolute roughness of the pipe.
