A₁ = 8 cm² = 8×10⁻³ m²
A₂= 10 cm² =1×10⁻⁴ m²
Q= 2 l/s = 2dm³/s = 2×10⁻³ m³/s
Dit= v₁ dan v₂
Jwb=
Q= A₁.v₁
2×10⁻³=8×10⁻⁴.v₁
v₁= 2,5 m/s
Q= A₂.v₂
2×10⁻³=1×10⁻³.v₂
v₂=2 m/s
A₁ = 8 cm² = 8×10⁻³ m²
A₂= 10 cm² =1×10⁻⁴ m²
Q= 2 l/s = 2dm³/s = 2×10⁻³ m³/s
Ditan
v₁=......?
v₂=.....?
penyelesaian
Q= A₁.v₁
2×10⁻³ = 8×10⁻⁴.v₁
v₁= 2,5 m/s
Q= A₂.v₂
2×10⁻³=1×10⁻³.v₂
v₂=2 m/s
jadi kecepatan aliran adalah 2,5m/s dan 2m/s
