LEARN MORE REMARKS Compare this to the volume flow rate in the absence of any viscosity. Using Bernoulli's equation, the calculated volume flow rate is approximately five times as great. As expected, viscosity greatly reduces flow rate. QUESTION If the radius of a tube is doubled, by what factor will the flow rate change for a viscous liquid?
