Hydrostatic Balance
Now that we have the Ideal Gas Law at our disposal and know
something about how temperature varies with height in the atmosphere, we are nally equipped to consider in detail how and why

Similitude
Not all practical fluid mechanics and hydraulic
problems can be solved by analysis alone
The solution of many problems require a
combination of analysis and experimental data
Engineers need to be acquainted with the techniques
for design and ex

1. Describe the principle of operation of the following types of viscometers.
a. Redwood Viscometers.
b. British Standard 188 glass U tube viscometer.
c. British Standard 188 F

Concept of Boundary Layer
Ludwig Prandtl (1875-1953) in 1904 proposed the concept of
boundary layer:
Within which viscosity is important
Outside of which friction is unimportant, therefore fluid can be
assumed to be ideal or inviscid
Laminar and Turbulent

Water at 60o C flows in a 15 mm diameter copper tube (e = 0.0015 mm) at 0.06
L/s. Find the head loss per 10 m given f = 0.0304. What is the centerline velocity,
and what is the value of v?

The equations of uid motion
In order to proceed further with our discussion of the circulation of the atmosphere, and later the ocean, we must develop some of the underlying
theory governing the motion of a uid on the spinning Earth. A dierentia
