Catalog Course Description:
3 hours. Fundamental concepts and properties of fluids; hydrostatics; basic equations of fluid flow
in differential and integral forms. Dimensional analysis, potential and viscous flow. Viscous
boundary layers, pipe flow, turbulence, and fluid flow corre
lations for objects of simple shape.
Prerequisite(s)
:
MATH 2730 and
MATH 33
10 or MATH 3410
Required for the BS degree in Mechanical and Energy Engineering at UNT.
Course Objectives:
1.
Demonstrate their knowledge via assignments, quizzes, and exams
that
require of applying math
(vector calculus and differential equations) and fundamental science (conservation of mass,
momentum) to fluid mechanics problems.
2.
Identify engineering problems and use the basic laws of fluid mechanics to solve these problems
.
3.
Draw a free

body diagram of a fluid statics problem, convert a pressure distribution into a
resultant force, and solve for unknown forces.
4.
Apply the conservation of mass and momentum to a fluid control volume.
5.
Use the Moody diagram to find the friction f
actor and solve for the pressure drop due to
friction.
6.
Understand and apply Bernoulli’s equation.
7.
Find the total acceleration of a fluid particle.
8.
Be familiar with the derivation of the Navier

Stoker equations.
9.
Determine dimensionless groups from a list of
variables using the Buckingham Pi theorem.
