Which outcome reduces accuracy when estimating hydraulic diameter using an oversimplified equation in calculating pressure drops through irregularly shaped microfluidic analytical devices?

💡 Explanation

Increased wall shear stress variation results because inaccurate hydraulic diameter estimates using Poiseuille's equation misrepresent the Channel's Flow Profile within the microfluidic device. Therefore, shear stress estimates become unreliable, rather than other outcomes which require different fluid dynamic equations.
