A.36 B.28 C.2 D.1
2.8.400m^3/menit=.......dm^3/detik
A.140 B.1.400 C.14.000 D.140.00
3.Debit pipa sebuah air adalah0,8liter/jam.Berapa cm^3/menit debit pipa tsb
A.13,4 B.13,3 C.13,2 D.13,1

Answer 1

1. Debit = V ÷ W
= 3600 ÷ 1800
= 2 liter/detik { C }
nb. 1 jam = 3600 detik
1/2 jam = 1800 detik

2. 8400m3/mnt = (8.400.000 ÷ 60)
=140.000dm3/detik ={ D }
nb. 1 m3 = 1000 dm3
1 mnt = 60 detik
3. 0,8 liter/jam = (800 ÷ 60)
= 13,33 cm3/menit
= 13,3 cm3/menit { C }
nb. 1 liter = 1 dm3
1 dm3 = 1000 cm3
1 jam = 60 menit
