Porszę o obliczrnie - wziąć pod uwagę jednostki!!! (najlepiej w m2/s)
1dm³ = 1dm * 1dm * 1dm = 100mm * 100mm * 100mm = 1 000 000mm³
1m³ = 1m * 1m * 1m = 1000mm * 1000mm * 1000mm = 1 000 000 000mm³

6 s
379,94mm² = (379,94 : 100)cm² = 3,7994cm² = (3,7994 : 10 000)m² = 0,00037994m² ---- tyle otrzymamy w mianowniku
0,00011(3)m³/s : 0,00037994m² = 11,(3) : 37,994m/s = 0,298.....m/s = ~ 0,3m/s
1 dm³ = 0,001 m³
1 min = 60 s
1 mm² = 1,0 ·10⁻⁶ m²
v = 6,8(dm³/min)/379,94(mm²) = 6,8·0,001m³/60s : 379,94·10⁻⁶m² = 0,298 m/s ≈ 0,3 m/s
