Why Fluids?
Brainstorm
a list of engineered or biological
devices that require an understanding of
fluids to explain how they work.
What fluids properties do you think would
be important in explaining each of the
devices?
Course Topics
Fluid
Properties
Statics
Bernoulli Equation
Explain
why a ping-pong ball can be held in an
air jet
Control Volume Analysis
Quantify
the effects of mass, momentum and
energy flux
Explain why lawn sprinklers rotate
Course Topics
Pipe
Flow
How
big does the tunnel have to be that carries
drinking water into NYC?
External
Flows
How
much power does it take to drive a new
VW beetle at 100 kph?
Open
Channel Flow
How
deep will the water be in Fall Creek
during a spring snow melt caused by a warm
rain?
My Goals for the next six
weeks...
That
each of you develop an intuition for
the fundamental principles of fluid
mechanics
That you leave this course saying, “Fluids
makes sense” and “I can tackle fluids
problems.”
That we have an enjoyable 6 weeks learning
together
