Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have two problems that I'm stuck on. Not really sure how to get the answer/what equation to use. Can someone help me?

1) The blood speed in a normal segment of a horizontal artery is 0.13 m/s. An abnormal segment of the artery is narrowed down by an arteriosclerotic plaque to 1/4 of its normal cross-sectional area. What is the difference in blood pressure between the normal and constricted segments of the artery?

2) Oil is flowing with a speed of 2.42 m/s through a pipeline with a radius of 0.132 m. How many gallons of oil (1 gal = 3.79 x 10-3 m3) flow in one day?
