If the Test Section area has an air speed of 10 m/s, what would be the air speed at the Air Intake area
1 answer:
The speed of air at the intake area is (m/s).
The continuity equation is used to determine the flow rate at different sections of a pipe or fluid conduit.
The continuity equation is given as;
- Let the intake area = A₁
- Let the velocity of air in intake area = v₁
- Let the area of the test section = A₂
- Velocity of air in test section, v₂ = 10 m/s
The speed of air at the intake area is calculated as follows;

Answer:
s = 20 m
Explanation:
given,
mass of the roller blader = 60 Kg
length = 10 m
inclines at = 30°
coefficient of friction = 0.25
using conservation of energy
u = 9.89 m/s
Using second law of motion
ma =μ mg
a = μ g
a = 0.25 x 9.8
a = 2.45 m/s²
Using third equation of motion ,
v² - u² = 2 a s
0² - 9.89² = 2 x 2.45 x s
s = 20 m
the distance moved before stopping is 20 m
