in the attached equations sheet, derive the corresponding
expressions for the minimum fluidising velocity, umf, for both
equations and explain their meaning.

The human body contains about 10^(14) cells, and the diameter of
a typical cell is about 10 micrometers. Like all ordinary matter,
cells are made of atoms; a typical atomic diameter is 0.1
nanometers. I have all of the correct answers, but I do not know
how to get to these answers or solve them on my own. I would like
to get explanations (why?) and see how it should be done (math
being done). a) How does the number...

The aorta has a diameter, d. Blood has a viscosity,
?, 4.00 x 10-3 Pa.s and a density of 1025
kg.m-3.
1. Using Poiseuille's equation, calculate the pressure drop per
unit length along the aorta. Assume that the aorta has a diameter
of 2.63 cm and that blood flows along the aorta at an average speed
of 0.255 m.s-1.
2. Poiseuille's equation does not hold if the flow velocity is
high enough that turbulence sets in. The onset of turbulence...
