Which of these equations is used to calculate the water velocity inside of a pipe?

Civil Engineering : Waste Water Engineering - Quiz(MCQ)

A=Q/I

L=C*Q

Q=A*V

V=0.408 Q/ DÂ²

Correct Answer : V=0.408 Q/ DÂ²

Explanation : The first formula is used to calculate the infiltration area. The third formula is used to calculate the load of wastewater. The fourth formula is used to calculate the rate of flow. The second formula is used to calculate the velocity of flow inside of a pipe (V) where Q stands for flow rate of water inside pipe and D stands for pipe diameter (inside).
