Answer:
Q= 4.6 × 10⁻³ m³/s
actual velocity will be equal to 8.39 m/s
Explanation:
density of fluid = 900 kg/m³
d₁ = 0.025 m
d₂ = 0.05 m
Δ P = -40 k N/m²
C v = 0.89
using energy equation

under ideal condition v₁² = 0
v₂² = 88.88
v₂ = 9.43 m/s
hence discharge at downstream will be
Q = Av
Q =
Q =
Q= 4.6 × 10⁻³ m³/s
we know that

hence , actual velocity will be equal to 8.39 m/s
The answer mostly likely is: “1” due to the fact it is well ordered, and follows a similar thought process, best of luck!
Answer:
Time taken by airplane to cover given distance = 2 hour
Explanation:
Given:
Distance cover by airplane = 1,000 miles
Velocity of airplane = 500 miles per hour
Find:
Time taken by airplane to cover given distance
Computation:
Time taken = Distance / Velocity(Speed)
Time taken by airplane to cover given distance = Distance cover by airplane / Velocity of airplane
Time taken by airplane to cover given distance = 1,000 / 500
Time taken by airplane to cover given distance = 2 hour
