dibantu ya tolongg pentinggg sekali,terimakasih

400liter = 400dm^3

debit air = 0.04 dm^2 x 20dm/s
debit air = 0.8 dm^3/s



400/0.8= 500s =8,3 menit

• debit

V = 400 L = 4×10^-1 m³
A = 4 cm² = 4×10^-4 m²
v = 2 m/s
t = __?

debit
Q = V / t
Q = A v

samakan
A v = V / t
4×10^-4 • 2 = 4×10^-1 / t
10^-4 • 2 = 10^-1 / t
10^-3 • 2 = 1 / t
t = 1 / (2×10^-3)
t = 10³ / 2 = 500 s
t = 500/60 = 8⅓ ≈ 8,3 menit ←
