Bernoulli's Equation & Flow
GATE 2010
Medium

The maximum velocity of a one-dimensional incompressible fully developed viscous flow, between two fixed parallel plates, is 6 ms⁻¹. The mean velocity (in ms⁻¹) of the flow is

  • A2
  • B3
  • 4
  • D5

Explanation

For fully developed laminar flow between parallel plates, Vavg=(2/3)Vmax=(2/3)(6)=4 m/s.
