Question
Download Solution PDFCalculate the head loss due to friction using Darcy formula when water flows through a pipe of 100 mm in diameter and 50 m long with velocity of 2 m/s. Assume f = 0.005 and g = 10 m/s2.
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) = 100 mm
Length (L) = 50 m
The velocity of flow (v) = 2 m/s
Friction factor (f) = 0.005 × 4
Head loss due to friction (hf) =?
\(h_{f}={0.005× 4 ×50× 2^2\over 2× 10× 0.1}\) = 2 m
