  • Ket.
    D = Debit
    V = Volume
    W = Waktu
    dm³ = liter
    cm³ = cc/ml (mili liter)
    m³ = kl (kilo liter)
    m² = ca (Centi Are)
    hm² = ha (Hektar Are)
    dam² = are

    1. Mencari debit
    D = V : W
    V = 30 liter
    W = 5 menit
    D = 30 liter : 5 menit
    D = 6 dm³/menit = 0,1 dm³/detik
    2. Mencari waktu
    W = V : D
    V = 240 dm³
    D = 80 liter/jam
    W = 240 dm³ : 80 liter/jam
    W = 3 jam
    3. Mencari volume
    V = D x W
    D = 20 dm³/menit
    W = 6 menit
    V = 20 dm³/menit x 6 menit
    V = 120 liter
    4. Mencari volume
    V = D x W
    D = 30 liter/menit
    W = 30 menit
    V = 30 liter/menit x 30 menit
    V = 900 liter
    5. Mencari debit
    D = V : W
    V = 72 dm³
    W = 2 jam = 7.200 detik
    D = 72 dm³ : 7.200 detik
    D = 0,01 liter/detik
    *Semoga membantu ^_^
