Talk:Friction loss

BSamson-NJITWIL

Proposed Revision for this article:

1.) Edit the definition to clearly identify what Friction Loss is.

2.) Edit the definition to delete incorrect jargon such as "limited space".

3.) Give a brief summary of why Friction Losses occur.

4.) Write the Darcy Weisbach equation (the standard equation for calculating head loss due to friction).

5.) List sources used for this edit. — Preceding unsigned comment added by BSamson-NJITWIL (talk • contribs) 00:55, 9 December 2012 (UTC)

The section "Firefighting Applications" contains the following statement: "Ultimately, as the pressure created by a fire pump goes higher and higher the amount of water actually flowing through a hose to a given point lessens, threatening firefighting operations." For a given hose of a fixed length and diameter any increase in supply pressure will result in an increase flow rate, so the above statement is not correct. As pointed out by BSamson the flow follows the Darcy Weisbach equation which shows the continuing proportionality between the pressure drop and the square of the flow rate.

Clean-up edits and practical values for water

I did some clean-up editing and added practical values for water in PVC pipe.

The discussion of "Causes" of friction loss needs improvement. ArthurOgawa (talk) 13:39, 29 September 2015 (UTC)–ArthurOgawa (talk) 18:33, 5 October 2015 (UTC)
