a very dilute orange juice flows along a smooth tube (0.010m in diameter) with a maximum flow rate of 0.1m/s.
a) State the assumptions needed to solve the problem b) Calculate the pressure gradient Equations: Vmax = (Change in P * R^2)/(4*viscosity*L) Reynolds number = (density*D*v)/viscosity I am a bit confused about how to solve this as I havn't done any engineering before. This is what I have come up with so far: a) Assume laminar flow  Reynolds number = 2100 Assume newtonian fluid Assume density of dilute orange juice is same as for water. b) Use Reynolds number to solve for viscosity. Then solve for change in pressure/L using Vmax equation. Any help would be appreciated!
