CE330 Exam 1 Review

Water resources engineering is only concerned with the management of water quantity and not water quality.

• True

• False

What are the two main processes that water resources engineers engineer?

• hydraulics

• geology

• hydrology

• pedology

• ecology

The velocity in a pipe is smallest near the pipe wall.

• True

• False

Which of the following statements is NOT true?

• Pipe friction is linearly proportional to pipe length.

• Pipe friction is a function of the mean flow rate in the pipe.

• Pipe friction is related to the roughness of the pipe under turbulent flows.

• Pipe friction is dependent on the pressure under which the water flows.

Each of the friction head loss equations we have considered can be expressed in the form h_f = KQ^m.

• True

• False

Minor head loss is always less than major (friction) head loss in a pipeline system.

• True

• False

Which types of pipeline problems generally require iterative solutions?

• Type 1

• Type 2

• Type 3

For pipeline problems, solutions for which variable(s) do NOT require iterative solutions?

• pipe diameter

• head loss

• flow rate

In a classical 3-reservoir problem, what variable must be guessed in order to begin the iterative solution process?

• Total head that the junction

• Elevation head at the junction

• Total head at the reservoirs

• Velocity in the pipes

In a classical 3-reservoir problem, what is a good initial estimate of the total head at the junction?

• Elevation of the lowest reservoir

• Elevation of the highest reservoir

• Elevation of the middle reservoir

• Elevation of the junction
