 Dec 3rd 2017, 06:47 AM #1 Junior Member   Join Date: Dec 2017 Posts: 1 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)
