Unformatted text preview: calculations use an approximation of the supertanker as shown in the figure. • Calculate the force required to keep the tanker moving at U • Confirm you used the correct approximation for drag coefficient (HINT: use Reynolds No.) • Determine the power required to overcome the skin friction drag 4. Determine the bulk velocity ( u b ) and pressure drop ( Δ p ) in a nonNewtonian fluid flow (unidirectional, viscous) in a pipe of radius a . The velocity profile for a nonNewtonian fluid is: ? = ? ±²³ ∙ 1 − ´ µ ² ¶ · +1 · ¸ with: ? ±²³ = · · +1 ∙ ´− 1 2 ∙ ∆¹ º» ¶ 1 · ∙ ² · +1 · NOTE: n > 1 for shear thickening; n < 1 for shear thinning; n = 1 for Newtonian. K is a constant used to help describe the apparent viscosity of the liquid at any particular shear rate....
