Q.	The formula for hydraulic diameter is
A.	4a/p
B.	4ap
C.	4av
D.	4v
Answer» A. 4a/p
Explanation: hydraulic diameter handles the flow in non-circular channels and tubes. the most suitable term to calculate the hydraulic diameter for a round tube is dh= 4a/p. where ‘a’ is the cross-sectional area and ‘p’ is the wetted perimeter.
