3. Consider a horizontal pipe that has an inner diameter - 4 cm. It is filled with 20C water that is flowing in the longitudinal direction at 0.5 cm/sec in the very center. a. How fast are the molecules 1 cm from the edge of the pipe moving? b. Now change the fluid to 20C pentane under the same conditions. How fast are the molecules 1 cm from the edge of the pipe moving? c. If the pipe is 3m long and is being pumped at 202,650 Pa into a bucket open to the air, how long will it take to add 3 litres to the bucket? (Ignore evaporation.) i. Assume we are pumping 20C water ii. Assume we are pumping 20C pentane
