The axial velocity profile of a laminar, incompressible and fully-developed flow in a circular pipe of radius (R) is given as π’π§= β 1 4π ππ ππ§π 2 (1 β π2 π 2), where r, π§, π, and π are radial direction, axial direction, fluid viscosity, and pressure, respectively. If the average velocity of the flow is given by π’π§,ππ£π= 1 πΎ(β π 2 π ππ ππ§), then the value of K (answer in integer) is ______.
Answer: 8
