solving equation using HP-33s calculator

[peexpress]

Anyone used HP 33s calculator for the exam?

I have a question on inputting equations into my HP-33S calculator.

For example: for pipe flow in series using Darcy-Waback equation, how do you enter so many sets of f, L, and D?

Thanks a lot!

This topic has been covered before and the consensus is if you are not an expert at using the HP 33 dont bother with the programming. It just adds another level of difficulty and out of all the equations that would be helpfull you may only need a couple. I use the HP but do not program.
