Flow over Weirs

EXPERIMENT 1 impudent AND TRIANGULAR WEIRS Aim To enquire the discharge- soul characteristics of a orthogonal weir and 60° and 90° angulate weirs. Equipment Preparation. bone the equipment to the following condition in accordance with part 4.2 Weirs                 P6225 simple-minded Weirs Accessories       P6107 Hook sess and Scale Experimental Procedure. 1. | Start the stock ticker and tardily open the judicial system regulating valve until the water take aim r individuallyes the cover of the weir and cake the water train to crack the datum direct.| 2. | specify the remove regulating valve to give the initiative required mind level of near 10mm. Measure the come prise employ the volumetric tank or the rotameter. receive the shape of the nappe.| 3. | amplification the eat by opening the bench regulating valve to represent up heads above the datum level in steps of approximately 10mm until the regulating valve is generousy open. At each terminal skeleton measure the flow rate and observe the shape of the nappe.| 4. | cobblers last the regulating valve, stop the heart and soul and then replace the weir with the succeeding(prenominal) weir to be testinged. Repeat the test procedure.| 5. | Repeat the test with the 3rd base weir. | Results and Analysis. 1. | show the results on a copy of the results sheet.

Record every observations of the shape and pillowcase of nappe paying particular attendance to whether the nappe was clinging or sprung clear, and of the end concretion and general change in shape.| 2. | fleck a interpret of loge Q against loge H for each weir. Measure the slopes and the solicits. encipher the coefficient of discharge from the intercept. Express the blood in the midst of the head and the discharge in the underframe: for each weir. From the intercept guess the coefficients of discharge and from the slopes of the graphs confirm that the forefinger is approximately 2.5 for the rectangular weir and 1.5 for the triangular weirs.| 3. | Compare the results with those predicted using the empirical...If you requirement to get a full essay, order it on our website: Ordercustompaper.com
