2 Company1290 Friction Loss For Water At 60 F Per 100 Feet Of PipeNew Schedule 40 Steel Pipe - The Friction values are from the Hydraulic Institute Pipe Friction Manual. (Copyright 1961). No allowance has been made for age, differences in any abnormal conditions of interior factor of safety must be estimated from the conditions and the requirements of each installation. For average new installations it is suggested that at least 15% be added to these Friction loss values as a reasonable factor of Year Old Pipe - The Friction values for Old Pipe are based on Williams and Hazen coeffi cient of C=100. Values for 3 inch and larger sizes are for cast iron pipe; smaller sizes refer to steel pipe.

3 For existing older type installations, these higher values are generally used for estimating Friction Lines - To keep raw sewage in suspension in force mains, velocities above 2 feet per second are generally per Minute " Pipe " Pipe1" Pipe1 Pipe1 " PipeNew Steel PipeSchedule 4015 YearOldLinePipeNew Steel PipeSchedule 4015 YearOldLinePipeNew Steel PipeSchedule 4015 YearOldLinePipeNew Steel PipeSchedule 4015 YearOldLinePipeNew Steel PipeSchedule 4015 YearOldLinePipeVelocityFeetperSecondVelo cityHeadto inFeetVelocityFeetperSecondVelocityHeadt o inFeetVelocityFeetperSecondVelocityHeadt o inFeetVelocityFeetperSecondVelocityHeadt o inFeetVelocityFeetperSecondVelocityHeadt o 90 Engineering Data9 Data SECTION PAGE DATEUSA: (937) 778-8947 Canada.
