In a laminar flow between two static parallel plates, the velocity at mid-point is found to be 2.0 m/s. If the space between the plates is 10 cm, then the discharge per unit width (in m3/s/m) will be

Detailed Solution for Test: Laminar Flow in Pipes - 1 - Question 1

The average velocity
= 2/3 x 2 = 4/3 m/s
The discharge per unit width
= 4/3 x 0.1 = 0.13 m3/s/m
