In a laminar flow, the velocity distribution over a flat plate is given by u = y-y² where u is the velocity in m/s at a distance y (in m) above the plate and µ for the given fluid is 0.84 Ns/m2. The shear stress at a location 0.35 m above the plate is K times the shear stress at a location 0.25 m above the plate.
Which of the following statements is/are correct?
1
Velocity gradient at 0.35 m location is 0.50
2
Velocity gradient at 0.35 m location is 0.30
3
Shear stress at boundary of plate will be zero.
4
The value of K would be 3/5
