When physicians diagnose arterial blockages, they quote the reduction in flow rate. If the flow rate in the artery has been reduced to 10% of its normal value by a blood clot and the average pressure difference has increased by 20% by what factor has the clot reduced the radius of the artery.

2. Relevant equations

3. The attempt at a solution

Totally lost on how to start this one, I kind of think that the following equation has something to do with it, bu not sure

D=sqrt(4Q/piv) where v= velocity Q = volumetric flow rate
