Abstract

The field practicum enabled the application of the principles and theories in irrigation engineering in the evaluation of the newly constructed sprinkler irrigation system in the East Course of Wack Wack Golf and Country Club. The study involved the observation on the actual layout of the irrigation lines from the main pump to the sprinkler heads of the laterals as well as evaluation of the efficiency of the sprinkler system through determining the coefficient of uniformity (CU), distribution uniformity (DU) and potential water application efficiency (known as potential application efficiency of the low quarter, PELQ). It also involved the verification and comparison of the computed and actual pipe size and power requirement of the East Course. The CU, DU and PELQ of the system was accomplished by performing catch can test on Hole 5 of the East Course. Scobey’s equation was used to verify the pipe size and power requirement of the whole system. The computed sizes were then compared with the actual sizes used in the East Course. The velocity in the longest straight line pipe of the East Course was also computed to check for the possibility of the occurrence of water hammer. The average value of the three parameters: CU, DU and PELQ of the system were 72.0%, 58.0% and 53.6% respectively. The computed values of the three parameters were below the standard values for CU, DU and PELQ (80% for CU and 70% for DU and PELQ) as recommended by Schwab (1993) and the Irrigation Association (2003). The computed pipe sizes for the 2-inch lateral line, 10-inch main line, 8-inch main line, 6-inch main line and 4-inch main line were smaller (1.15 inches, 6.19 inches, 5.49 inches, 4.96 inches and 3.5 inches respectively) compared to the actual pipe sizes used in the system. This indicates that safety factors were applied in the selection of pipe sizes used in the sprinkler system. Also, safety factors were applied in the selection of pump to be used. The computed value for the pump size (75 hp) is lower than the actual pump size (100 hp) used. Based from the results of the field practicum, there was non-uniform water distribution in the East Course during the period that the field practicum was conducted. This was because of the low pressure that was observed in the pipes during operation. Lower pressure was used since the East Course was still under the renovation process during the conduct of the field practice. The pipe sizes and pump rating used was found appropriate for the sprinkler system. The possibility of the occurrence of water hammer in the longest straight line pipe of the East Course was also found unlikely since the actual velocity of water (1.2 m/s) was lower than the maximum water velocity (1.5 m/s) in the pipe in order to prevent the occurrence of water hammer as recommended by Haman, et al. (2009).
