A medical technician is trying to determine what percentage of a patient's artery is blocked by plaque. To do this, she measures the blood pressure just before the region of blockage and finds that it is 1.20×104 Pa, while in the region of blockage it is 1.15×104 Pa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at 30.0 cm, and the specific gravity of this patient's blood is 1.06.What percentage of the cross-sectional area of the patient's artery is blocked by the plaque?
I would appreciate any kind of help, hints in how to start the problem thank you.

Use Bernoulli’s principal
V^2/2 + P/d= constant
V = fluid velocity along the artery
P = pressure along the flow (non turbulent)
d = blood’s density
