Goals:

- Know what NPSHR is and how to avoid frying a pump.
Reading
- The class notes.
- BS&L, chapters 6&7
Additional Readings:
Our friends from Australia have put together a 'Pump School' which has all the
information you would ever want to know about sizing pumps and reading pump
curves. The link to this information is
here.
It would be a -really- good idea to review it if you are ever in charge of sizing a pump!
Samples of pump curves (for Sykes pumps) are given
here.
Just click on one of the links for a .pdf file such as we looked at in class. 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!
