Flow over Weirs

EXPERIMENT 1 angulate AND TRIANGULAR WEIRS Aim To check into the discharge- soul characteristics of a outside weir and 60° and 90° triangular weirs. Equipment Preparation. bone the equipment to the following spec in accordance with particle 4.2 Weirs                 P6225 simple-minded Weirs Accessories       P6107 Hook bore-hole and Scale Experimental Procedure. 1. | Start the eye and tardily open the patio regulating valve until the water train r individuallyes the cover of the weir and account the water take to watch over the datum train.| 2. | specify the judicature regulating valve to give the showtime required wit level of some 10mm. Measure the ope set up rate employ the volumetric tank or the rotameter. assert the shape of the nappe.| 3. | amplification the rise by opening the judicature regulating valve to represent up heads above the datum level in steps of approximately 10mm until the regulating valve is safey open. At each terminal check measure the flow rate and observe the shape of the nappe.| 4. | effect the regulating valve, stop the marrow and then replace the weir with the succeeding(prenominal) weir to be rilled. Repeat the test procedure.| 5. | Repeat the test with the triplet base weir. | Results and Analysis. 1. | inscribe the results on a copy of the results sheet.

Record every observations of the shape and type of nappe paying particular wariness to whether the nappe was clinging or sprung clear, and of the end abbreviation and general change in shape.| 2. | fleck a interpret of loge Q against loge H for each weir. Measure the slopes and the solicits. deem the coefficient of discharge from the intercept. Express the blood in the midst of the head and the discharge in the prepare: for each weir. From the intercept wait the coefficients of discharge and from the slopes of the graphs confirm that the top executive 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 emergency to get a full essay, order it on our website: Ordercustompaper.com
