http://www.elkhartbrass.com/files/aa/downloads/catalog/catalog-f2-T.pdf Towards the bottom of the file there is hose friction loss and some other info http://www.elkhartbrass.com/downloads/performance
I have a couple more around here... Not sure if the FD is requiring you to prove end of hose pressures. I have only used a friction loss for the hose itself, or at least added it to the required PSI at the hose valve i.e. 132 PSI minimum required instead of 100 PSI or in your case a loss for the footage. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Greg McGahan Sent: Wednesday, April 06, 2011 1:10 PM To: [email protected] Subject: HW for hose If you have to calculate a manual standpipe, what HW coefficient do you use for standard fire hoses? and what internal diameter is a 3" hose?
