Question

A pvc pipe with half centimeter diameter what is its friction constant

Answer 1

1 ft (foot) = 0.3048 m
1 ft/s = 0.3048 m/s
1 gal (US)/min =6.30888x10 -5 m3 /s = 0.0227
m3 /h = 0.0631 dm3 (liter)/s = 2.228x10 -3 ft 3/
s = 0.1337 ft 3 /min
1 psi/100 ft = 2.3 ftH 2 O/100 ft = 2288
mmH 2 O/100 ft = 22.46 kPa/100 m
Note! Velocities should not exceed 5 feet per
second.
