Water of kinematic viscosity v = 1 centistoke flows through a 10 mm diameter pipe. The critical flow in this pipe would correspond to a discharge of approximately

Friction factor f in laminar and turbulent flow in a pipe varies as Re-1 and Re-0.25 respectively. If V\s the average velocity, the pressure drop in a horizontal pipe for laminar and turbulent flow respectively will be proportional to
The critical value of reynolds number for transition from laminar to turbulent boundary layer in external flows is taken as
In a fully turbulent flow through a rough pipe, the friction factor ‘f’ is (Re is Reynolds number and ξs/D is relative roughness)
Using the Prandtl's mixing length concept, how is the turbulent shear stress expressed?
