What is the volume flow rate for water (viscosity= .0010 Pa×s) through a length of pipe L= 0.60m and pipe radius r= 1.03cm if the pressure difference across this length of pipe is 5.2 kPa? Note that 1 kPa= 1000 Pa. What would the volume flow rate be if the same pipe had a radius that is reduced by 21% (i.e. the radius is 79% of its previous value)? Let's call this flow rate Q1. What is the ratio of Q1 to the original flow rate Q? Express this as a decimal number.
