A pipeline is designed to deliver $20 \mathrm{~L} / \mathrm{s}$ of an oil (kinematic viscosity $=6 \times 10^{-6} \mathrm{~m}^2 / \mathrm{s}$ and specific gravity $=0.9$ ) under the laminar flow condition. The minimum diameter of the pipe will be ____________ (in m, $\text{rounded off to two decimal places).}$
