3. Consider a horizontal pipe that has an inner diameter =4cm. It is filled with 20C water that is flowing in the longitudinal direction at 0.5cm/sec in the very center. a. How fast are the molecules 1cm from the edge of the pipe moving? b. Now change the fluid to 20C pentane under the same conditions. How fast are the molecules 1cm from the edge of the pipe moving? c. If the pipe is 3m long and is being pumped at 202,650Pa 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 3. Consider a horizontal pipe that has an inner diameter =4cm.
