(1) Why the airs in the pipeline need
to be ruled outbefore the experiment? How to judge the air in the
pipeline has been excluded.
(2) Construct the relationship plots
of λ~ Re and ζ~ Re, respectively, and compare to
that of Blasius formula.
(3) How does readings of the pressure
gauge and vacuum gauge change when the flow control valve is
changed?
(4) How to choose a centrifugal
pump?
