A reboiler contains 1934 tubes, where each tube has a 0.57 inch inner diameter and a length of 15 ft. The water flow to the reboiler tubes is provided by a pump that produces a constant 5.8 psig different across the reactor. Given a deposition rate of 0.00040 in/hr, how much does the flow rate drop in 25.8 hrs? Assume the water is at room temperature and laminar flow (even though it is not). Report your answer as a percentage of the original flow. So, a 10 percent drop is 90 percent of the original flow. (Hint: you can solve the problem without using all the provided information.)
