Question
Download Solution PDFWater flows through a pipe of 200 mm in diameter 60 m long with a velocity of 2.5 m/s. What is the head loss due to friction using Darcy's formulae ? (Assume f = 0.005)
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
Darcy-Weisbach Equation
\(h_{f}={fLv^2\over 2gD}\)
Where L = length of pipe
D = Diameter of pipe
v = Mean velocity of flow
f = Friction factor
\(h_{f}\) = Head loss due to friction
Calculation:
Given data:
Pipe diameter (D) = 200 mm
Length (L) = 60 m
The velocity of flow (v) = 2.5 m/s
Friction factor (f) = 0.005 × 4
Head loss due to friction (hf) =?
\(h_{f}={0.005\times 4× 60× 2.5^2\over 2× 9.81× 0.2}\) = 1.91 m
