Question

A fluid flows down a flat channel. The velocity profile is shown at right. Kinematic viscosity of the fluid equals 2 \times 10^{-3} \frac{m^{2}}{s} Specific gravity is 0.84. U- 6

m/s and h- 2.3 m. For reference, the standard density of water at 4 deg C to use in specific gravity calculations, if need be,is 1000 \frac{k g}{m^{3}} a) How do you convert kinematic viscosity to dynamic viscosity? b) What is the major equation that you will need to calculate shear stress that the fluid exerts on the fixed surface? ) What is the shear stress exerted by the fluid on the surface?
