8.7. Kesimpulan dan Saran

1. Kesimpulan

-(F2) akibat pancaran air adalah antara 0.14 N - 1.25 N

pancaran air adalah antara 0.01 N - 0.65 NJadi gaya yg dihasilkan pancaran fluida pd plat cekung lebih besardibandingkan pancaran fluida pada plat datar.

- Perbandingan F1/F2 pd plat cekung adalah antara 1.14 - 4.20Perbandingan F1/F2 pd plat datar adalah antara 2.19 - 45.69Perbandingan F1/F2 pd plat cekung lebih kecil dari pd plat datar

-(M) akibat pancaran air adalah antara 0.09 Kg/det - 0.23 Kg/det

pancaran air adalah antara 0.07 Kg/det - 0.23 Kg/det- Pengukuran volume air yang dihasilkan pada percobaan akan semakin besar,

waktu semakin besar dan jarak beban bertambah

2. Saran

- Sebaiknya menggunakan tempat dudukan yang khusus untuk alat agar selama melakukan pengukuran/pengamatan alatnya tidak goyang atau miring apalagi terjadiperubahan debit agar tingkat ketelitian pengambilan data lebih akurat

- Pengamatan sebaiknya dilakukan beberapa kali agar hasilnya lebih teliti dan pengaturan keseimbangan harus dilakukan lebih baik.

- Perubahan debit sebaiknya jangan terlalu besar.
