Equations for each velocity profile (mm min⁻¹)

Velocity profile (a): $u=5$

Velocity profile (b): $u=\left\{\begin{array}{c}5t\le \frac{T}{2}\\ 0t>\frac{T}{2}\\ \end{array}\right)$

Velocity profile (c): $u=\left|5sin\left(\frac{2\pi t}{T}\right)\right|$

Velocity profile (d): $u=\left\{\begin{array}{c}5sin\left(\frac{2\pi t}{T}\right)t\le \frac{T}{2}\\ 0t>\frac{T}{2}\\ \end{array}\right)$
