Answer: The question has some details missing which is the velocity profile .The velocity profile is given as u = (8y - 0.3y^2) mm/s
the shear stress on the fluid at y = 0.15 m = 6.80 x 10^-3N/m^2
Step-by-step explanation:
The detailed steps is the use of the relationship between the shear stress, viscosity and the velocity profile. appropriate differentiation and substitution were made to calculate the shear stress as is shown in the attachment.
