Question 48
CENAT2 marksNeeds review
A rough pipe of 0.5 m diameter, 300 m length and roughness height of 0.25 mm carries water (kinematic viscosity = 0.9×10⁻⁶ m²/s) with velocity of 3 m/s. Friction factor (f) for laminar flow is given by f = 64/Re, and for turbulent flow it is given by
, where, Re = Reynolds number, r = radius of pipe, k = roughness height and g = 9.81 m/s². The head loss (in m, up to three decimal places) in the pipe due to friction is ______Log in to check the answer
