1.	If the equation of a velocity profile over a plate is v = 5y^2 + y (where v is the velocity in m/s) determine the shear stress at y = 0. Given the viscosity of the liquid is 8.35 poise.(a) 0.830(b) 0.832(c) 0.835(d) 0.834I had been asked this question by my college professor while I was bunking the class.The doubt is from Classification of Fluids topic in division Fluid Flow and Mixing of Bioprocess Engineering
Answer» The correct choice is (c) 0.835 The best EXPLANATION: GIVEN Data: VELOCITY PROFILE v = 5y^2 + y; μ = 8.35 poise Substituting y=0 on the above equation, we get shear stress at RESPECTIVE depths. τ = 0.835
