ECI 141 – Assignment 2 Multiple Pipe Systems Fall, 2019 1. ECI 141 – Engineering Hydraulics Fall Quarter, 2019 Assignment # 2 – Multiple Pipe Systems 5 Problems – Due October 21, 2019 by 5:00 pm in the homework box in Ghausi Hall Problem 1 A pipeline with a diameter of 0.9 m divides into three 0.45 m pipes at elevation 120 m. Each of the three 0.45 m pipes run into reservoirs which have surface elevations of 90 and 30 m and 60 m respectively. The three pipes have lengths of 3.2, 4.8 and 6.8 km respectively. If 1.4 m 3 /s flows into the 0.9 m pipe, how will the flow divide? Assume that f= 0.017 for all pipes. Problem 2 Five 25 mm diameter pipes will conduct 2.4 l/s of water (20 ºC) between two reservoirs whose surface levels remain constant. The pipes are made of PVC. Find the diameter of a single PVC pipe that will carry the same flowrate between these reservoirs. How would this number be impacted if cast iron pipe were used instead? Z=90 Z=60 Z=30 Z=120

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
