K factor for pressure drop calculator
Posted: Thu Jul 29, 2010 8:06 pm
Hello everyone. I'm new to all of this, both the forum AND fluid dynamics in general, so forgive me please if I am asking a silly question about something that probably ought to be obvious to me. I've been trying to use the pressure drop calculator to calculate flow rate through a pipe and I'm in possession of 7 of the 8 factors I need to perform the calculation. The only one I am missing is the Resistance Coefficient or K factor. If somebody could help me out I'd really appreciate it. I've been trying in vain for the past two days to figure this out for myself but I'm stumped. The fluid is fresh water if that helps.
Also, I have a question regarding the kinematic velocity of water. As far as I'm aware the v factor of water is 1.66e-5 (ft2/s) at 40°F but I have absolutely no idea what the 'e-5' part represents. If someone could explain this to me I'd appreciate that very much too.
