Poiseuille's Law: A Visualization of Radius and Flow

Each of the following links shows a velocity profile and flow progress for a one second span for a variety of radius values. All other parameters are fixed at the standard values. So that you can compare how the new values affect the flow, each figure shows two different settings. The black portion represents the current settings, while the red portion represents the standard settings.

• a = 0.0165 mmHg: (10% increase)
• a = 0.01575 mm: (5% increase)
• a = 0.015 mm: (standard)
• a = 0.01425 mm: (5% decrease)
• a = 0.0135 mm: (10% decrease)
