Axial velocity profile π’(π) for an axisymmetric flow through a circular tube of radius π is given as, π’(π) π = (1 βπ π ) 1 π β where π is the centerline velocity. If π refers to the area-averaged velocity (volume flow rate per unit area), then the ratio π/π for π= 1 (rounded off to two decimal places) is ______________.
Answer: 0.32 to 0.34
