BAB V KESIMPULAN DAN SARAN 5. 1

Kesimpulan Dari hasil analisa yang dilakukan dapat disimpulkan ditabel berikut ini : Saluran Terbuka ( Open Channel )

Ambang Lengkung Q = 1591.247 hw = 88.403 HW = -5.000 Cw = 325.832 V1 = 14.734 Percobaan 1 V3 = 70.722 E1 = 23.064 E3 = 13.564 ∆E = 9.500 F = 0.240 Fr = 1.358 Q = 835.764 hw = 46.431 HW = -6.000 Cw = 160.556 V1 = 8.442 Percobaan 2 V3 = 46.431 E1 = 14.632 E3 = 5.632 ∆E = 9.000 F = 0.138 Fr = 0.813

Ambang Lebar Pent Q = 1671.528 hw = 92.863 HW = -37.500 Cw = 169.083 V1 = 17.688 Percobaan 1 V3 = 74.290 E1 = 26.446 E3 = 18.446 ∆E = 8.000 F = 0.288 Fr = 1.743 Q = 1506.695 hw = 83.705 HW = -38.000 Cw = 151.704 V1 = 16.741 Percobaan 2 V3 = 55.804 E1 = 24.285 E3 = 17.285 ∆E = 7.000 F = 0.273 Fr = 1.690

Ambang Tajam Q = hw = HW = Cw = V1 = Percobaan 1 V3 = E1 = E3 = ∆E = F = Fr = Q = hw = HW = Cw = V1 = Percobaan 2 V3 = E1 = E3 = ∆E = F = Fr =

934.413 51.912 -6.000 179.507 9.439 69.216 15.541 6.041 9.500 0.154 0.909 1671.528 92.863 -5.000 342.271 15.477 123.817 24.209 13.709 10.500 0.252 1.426

Saluran Tertutup ( Close Channel ) Pipa 1/2" → Pipa 3/4" Q = 0.0070 V = 4.0862 h = 1.6065 Percobaan 1 Re = 35511.9112 f = 0.0000089 Hf = 0.000400

Pipa 3/4" → Pipa 1" Q = 0.0086 V = 4.5487 h = 1.3230 Percobaan 2 Re = 48380.2251 f = 0.0000065 Hf = 0.000263

5.2

Saran Pada saat pengujian saluran terbuka maupun saluran tertutup hendaknya kita

memperhatikan arahan/petunjuk dari instruktur dan juga diperhatikan ketelitian pada saat pengujian aliran . karena saat pengujian banyak faktor yang harus dipahami dan dimengerti , misalnya pada saat pemasangan ambang dan juga melihat berapa tekanan air yang terjadi pada setiap ambang yang diuji . ketelitian saat mencatat hasil pengujian juga berpengaruh pada analisa yang kita kerjakan . karena itulah pengujian dan perhitungan hasil pengujian aliran menjadi tidak akurat .
