Question
1.4 litres of blood passes through an artery in 7 minutes. What is the rate of blood flow in millilitres per minute?
Solution
To find the rate of blood flow in millilitres per minute, you need to convert the volume of blood from litres to millilitres and then divide by the time in minutes.
Step 1: Convert litres to millilitres. 1 litre = 1000 millilitres So, 1.4 litres = 1.4 * 1000 = 1400 millilitres
Step 2: Divide the volume of blood by the time to find the rate. Rate = Volume / Time Rate = 1400 millilitres / 7 minutes = 200 millilitres per minute
So, the rate of blood flow is 200 millilitres per minute.

4. The speed of blood flow in an artery is given by Poiseuille’s law. The law says that blood flow is fastest in thecenter of the artery and slower at the edges. We can express this asS(r) =C(R2−r2).In this equationRis the fixed radius of the artery andSis the blood flow speed at a distancerfrom the centerof the artery.
