Chemical Engineering > GATE 2021 > Flow through Pipes
Consider a steady flow of an incompressible, Newtonian fluid through a smooth circular pipe. Let αlaminar and αturbulent denote the kinetic energy correction factors for laminar and turbulent flow through the pipe, respectively. For turbulent flow through the pipe αturbulent=((V0)/‾V)3 (2n2)/((3+n)(3+2n)) Here, ‾V is the average velocity, V0 is the centerline velocity, and n is a parameter. The ratio of average velocity to the centerline velocity for turbulent flow through the pipe is given by (‾V)/(V0) = (2n2)/((n+1)(2n+1))
For n=7 the value of αturbulent/αlaminar is _______ (round off to 2 decimal places).
For n=7 the value of αturbulent/αlaminar is _______ (round off to 2 decimal places).
Correct : 0.53
