Can not remember the formula for friction loss if there is any body that can please HELP
I need for 1 1/2,1 3/4, 2 1/2,5 inch hose. Been to long since I have used this knowledge and now I can not remember it.
My department is finishing a hose coefficient test involving every engine crew, a couple of very good hydraulics instructors, and Akron representatives. We've derived actual 1.75 hose coefficients at an average of around 10. The range we derived was 8.65 to 11.67.
Our live tests have shown that our 2.5 inch and 5 inch C's are so close to the IFSTA numbers it's not worth discussing the difference.
