Which equation is used to calculate the viscosity of a fluid in a capillary tube?

Which equation is used to calculate the viscosity of a fluid in a capillary tube?

Step 1: Understand that viscosity is a measure of a fluid's resistance to flow.
Step 2: Learn about capillary tubes, which are thin tubes that allow fluids to flow through them.
Step 3: Familiarize yourself with Poiseuille's law, which describes how fluids flow through a pipe or tube.
Step 4: Recognize that Poiseuille's law can be used to calculate the viscosity of a fluid by measuring the flow rate through a capillary tube.
Step 5: Use the formula from Poiseuille's law, which relates viscosity to the flow rate, tube radius, tube length, and pressure difference.
