Head Loss Calculation in Cast Iron Pipe
What is the head loss due to friction in a 720 m long cast iron pipe with a diameter of 200 mm and a flow velocity of 2 m/s?
Is the Hazen-Williams formula commonly used for calculating head loss in pipes?
Head Loss Calculation in Cast Iron Pipe
The head loss due to friction in a 720 m long cast iron pipe with a diameter of 200 mm and a flow velocity of 2 m/s is 7.925 meters. This value was obtained using the Hazen-Williams formula.
Utilization of the Hazen-Williams Formula
Yes, the Hazen-Williams formula is widely used for calculating head loss due to friction in pipes. It is based on the assumption of fully turbulent flow and takes into account the Hazen-Williams coefficient to represent the roughness of the pipe.
The Hazen-Williams formula is a commonly used method for determining head loss due to friction in pipes. It is represented by the equation:
hL = 10.67 × L × Q^1.85/C^1.85 × D^4.87
Where:
hL = head loss due to friction (m)
L = length of pipe (m)
Q = flow rate of water (m^3/s)
C = Hazen-Williams coefficient
D = diameter of the pipe (m)
In this case, with a pipe length of 720 m, a diameter of 200 mm, and a flow velocity of 2 m/s, the head loss due to friction was calculated as 7.925 meters using the given formula. The Hazen-Williams coefficient for cast iron pipes is approximately 120.85.
