1) Find the flow rate if the radius of the pipe is 2 inches and the velocity is 30 inches/second. First, find the answer in LaTeX: \frac{in^3}{\sec}i n 3 sec 2) Convert the previous answer to LaTeX: \frac{ft^3}{\min}f t 3 min. Keep in mind, you need to divide your previous answer by 12 for every inch dimension you are converting to feet. You also need to make sure you convert from seconds to minutes.

3) Convert the previous answer to GPM (there are 7.48 gallons in one cubic foot)

4) Oil that is being transported in pipelines travels anywhere from 3 to 8 mph. Assume there is a pipe with a diameter of 36 inches, and the oil in it has a velocity of 8.8 ft/sec. Find the flow rate in GPM.
