Water flows through a circular tube with a velocity of 2 m/s. The diameter of the pipe is 14 cm. Take kinematic viscosity of water 10^-6 m^2/s and density of water 1000 kg/m^3.
(a) 2.8*10^8
(b) 2.8*10^5
(c) 2800
(d) 28000
The question was posed to me during an internship interview.
I would like to ask this question from Flow of Viscous Fluid Through Circular Pipes topic in chapter Viscous Flow & Turbulent Flow of Fluid Mechanics
