WebTo summarize the laminar flow equation: The flow rate is directly proportional to the radius of the pipe. Thus, the small increase in pipe diameter can significantly increase the flow rate in the system. The flow rate is inversely proportional to the length of the pipe as well as the coefficient of viscosity of the fluid.
