For pipe lengths other than 100 feet the pressure drop is proportional to the length. Velocity is a function of the cross sectional flow
Thus, for 50 feet of pipe the pressdre drop is approximately one-half the value given area; thus, it is constant for a given flow rate
in the table . . . for 300 feit, three times the given value, etc. and is independent of pipe length.
]For pipe other than Schedule 40: v = v40 (dao/d)* and AP = 4Pa (daa/d)S where subscript
'10 refers to the conditions for schedule 40 pipe.
