摘要：Tujuan penelitian untuk mengetahui hasil optimasi pengukuran laju air dalam susunan peralatan eksperimen dinamika fluida sederhana. Penelitian memakai metode eksperimen berbasis 5 persamaan teoritis. Penelitian menunjukkan bahwa optimasi pengukuran hanya dapat dilakukan pada kajian perubahan posisi permukaan air,perbedaan pasangan diameter,perbedaan diameter pipa kedua,dan perbedaan keadaan pompa. Hasil pengukuran laju air untuk referensi 0,1,dan 2,masing-masing mempunyai kecenderungan khas bagi kajian perubahan besaran fisika dan,atau perbedaan kondisi fisika terkait. Laju air referensi 0,1,dan 2 makin kecil jika permukaan air makin rendah dengan rerata koefisien determinansinya,masing-masing 58%,76%,dan 73%. Laju air referensi 2 berbasis persamaan (3) dan (5),masing-masing makin besar jika diameter pipa referensi 2 makin besar dengan rerata koefisien determinansi 94% dan makin kecil dengan rerata koefisien determinansi 74%. Tendensi laju air referensi 0 dan 2 makin kecil ketika pompa dihidupkan dengan perubahan lebih besar,dibanding pompa tidak dihidupkan.
其他摘要：The research objective is to determine the results of optimization of water rate measurements in the arrangement of simple fluid dynamics experimental equipment. The study used an experimental method based on 5 theoretical equations. The research shows that the optimization of measurements can only be done on the study of changes in water surface position,differences in diameter pairs,differences in the diameter of the second pipe,and differences in pump conditions. The results of water rate measurements for references 0, 1,and 2,respectively,have a specific tendency for the study of changes in physical quantities and,or differences in the associated physical conditions. The reference water rates 0,1,and 2 are getting smaller,the lower the water level,with the mean coefficient of determination,respectively 58%,76%,and 73%. The reference water rate 2 is based on equations (3) and (5),each of which is greater if the diameter of the reference pipe 2 is bigger with a mean determination coefficient of 94% and the smaller,with a mean coefficient of determination of 74%. The tendency of the reference water rate 0 and 2 is getting smaller,when the pump is started,with a greater change,than the pump is not started.
