Maximum velocity of flow through a circular tube
Input(s)
\(p_{o}\): Pressure at Initial Point \((\mathrm{Pa})\)
\(p_{L}\): Pressure at Point \(\mathrm{L}(\mathrm{Pa})\)
R: Radius \((\mathrm{m})\)
\(\mu\): Viscosity \((\mathrm{kg} /(\mathrm{ms}))\)
L: Length (m)
Output(s)
\(v_{z m a x}\): Maximum Velocity \((\mathrm{m} / \mathrm{s})\)
Formula(s)
\[
\mathrm{v}_{\mathrm{zmax}}=\frac{\left(\mathrm{p}_{\mathrm{o}}-\mathrm{p}_{\mathrm{L}}\right) * \mathrm{R}^{2}}{4 * \mu * \mathrm{~L}}
\]
