In a two-dimensional vortex flow, the fluid flows in circular
paths around the center of the vortex. The magnitude of the
velocity decreases with distance from the center. The stream
function for a two-dimensional vortex centered at the origin is
ψ=ln sqrt(x^2+y^2) where the x--y plane is horizontal and x and y
are in meters. Show that continuity of the flow is satisfied and
determine the magnitude of the horizontal velocity at A, where
x=−0.2m, y=0.4m. Express your answer in...
The mechanics of blood flow in the body follows the laws of
fluid dynamics for tubes with a constant diameter and length. Which
statement is correct?
The flow of fluid in a tube depends upon the absolute pressure
at the beginning of the tube. The rate of fluid flow in a tube will
decrease if the pressure at the beginning is increased while the
pressure at the end of the tube stays the same. The greater the
resistance to flow...

Describe the flow of fluid through a nephron and to the external
environment. Include a simple labelled sketch with your
description
Please explain what cerebral spinal fluid (CSF) is, how it is
made (structures involved); and discuss its complete circulation
(as explained in the lecture). You must reply to at least one
student's explanation to receive credit.
