20.37 Poiseuille’s equation
Before you read this, I suggest you read posts 20.34 and 20.36. Poiseuille’s equation (highlighted in yellow above) enables us to calculate the rate of flow, R (volume divided by time), of a liquid of viscosity Ƞ in a narrow horizontal tube of radius a and length L, when there is a pressure difference, Δp,… Continue reading 20.37 Poiseuille’s equation
