please see the attached file the data and the assignment . Document Preview: 1/2 CE 367 – Hydraulics Laboratory (1 cr.) University of South Alabama Department of Civil Engineering Lab Assignment Information Number: 2 Title/Topic: Fluid Circuits I – Frictional Head Loss Due Date: One week from date of experiment Submission: Attachment to the corresponding assignment in Sakai Type: Individual lab memo Laboratory Demonstration Objectives 1. Evaluate the relative accuracy of the flow meter. 2. Compare experimental and theoretical values of frictional head loss using the Hampden Fluid Circuits Demonstrator (H-6925). Additional Information 1. Nominal inner diameter of 3/8’’ pipe: 0.430’’ (10.92 mm) 2. Nominal inner diameter of 1/2” pipe: 0.545” (13.84 mm) 3. Nominal inner diameter of 3/4” pipe: .785” (19.94 mm) 4. Nominal inner diameter of 1” pipe: 1.025” (26.04 mm) 5. Nominal roughness (Ks) value of drawn copper pipe: 5 x 10-6 ft (1.5 x 10-3 mm) 6. Apparatus fluid: tap water at room temperature Laboratory Procedure 1. Flow Meter Testing a. Work with your instructor to devise a plan for determining the accuracy of the flow meter 2. Frictional Head Loss a. Turn off the pump b. Isolate the 48-inch horizontal segment of the smallest pipe (3/8” diameter) ensuring that flow only goes through that pipe c. Turn on both digital pressure transducers and set the units to PSI d. Insert a gauge tap into the upstream and downstream pipe taps located 48 inches apart on the horizontal portion of the pipe e. Zero the readings on each gauge f. Turn on the pump and set/record the discharge in the system g. Record readings from each gauge every 30 seconds over a period of 3 minutes h. Repeat steps (a) – (g) for each of the four horizontal segments of pipe in the parallel arrangement Laboratory Assignment Please address the following in your lab memo: 1. Discuss the verification of the flow meter and comment on its accuracy. 2. Compare the experimental values of frictional head loss in the 3/8’’, 1/2”, 3/4”, and 1” pipes to those computed using theoretical concepts… Attachments: data.pdf Lab-2—Fluid….pdf
