Exclamation Urgent! Fluid Mechanics (Non-Newtonian Fluid)

A viscous, shear thickening material drains via gravity through a vertical pipe. If the pressure above and below the pipe is atmospheric and the pipe diameter is 50 mm, what is the length of time (s; 0DP) it will take to drain 5000 L of the material. The fluid properties are: density = 950 kg m^(-3), K = 0.50 Pa s^n, and an n = 1.50 s^(-1). Hint: assume laminar flow and apply Bernoulli's equation, solve to find the velocity and then the volume flow rate.

(Please show me the full working, greatly appreciated)

You mean "do your homework for you"? The problem suggests you treat this as "laminar flow". Do you know what that means? What is "Bernoulli's equation"?
