The main points of the lecture were
Goals:
After this class you should be able to:
- Calculate head loss in a piping network.
- Read a pump curve.
- Know what NPSHR is and how to avoid frying a pump.
Reading
- The class notes.
- BS&L, chapters 6&7
Additional Readings:
There are many sources of information on sizing pumps and designing piping networks
available on the web (although they do tend to disappear over time!). A comprehensive one is
given here.
It would be a -really- good idea to review it if you are ever in charge of sizing a pump!
Pump curves are also available on-line. As as example, those for Sykes pumps (such as we
looked at in class today) are given here.
Other links are
available on the web for pipe fittings. A useful one is given
here. Examination of
the data shows the K factors -do- change a little bit with diameter, but not very much!
