IrrigationPregunta 10 de 100
As irrigation pipe diameter decreases while flow stays the same, what happens to friction (pressure) loss?
a.Friction loss decreases
b.Friction loss stays the same
c.Friction loss increases
d.Friction loss becomes zero
Explicación
For a given flow rate, a smaller pipe forces water to move faster, and higher velocity dramatically increases friction loss along the pipe. This is why undersized pipe starves distant heads of pressure. Designers size pipe to keep velocity and friction loss within acceptable limits.
