Answer:
The volume air flow rate is
The output of the fan is 0.446 hp
Solution:
As per the question:
Diameter of the round duct, d = 0.30 m
Radius of the duct, R =
Pressure of the opening, P = 2.5 cm of water = 0.025 m of water
P =
Density of air,
Now, the velocity, v can be calculated as:
Now,
Volume rate of air flow is given by:
Now,
1 ft = 3.2808 m
Now, the output of the fan in horsepower (hp):
Power output, P' =
Now,
1 hp = 746 W
P' (in hp) =
Answer:
True
Explanation:
It could either be true or false because you dont really have to be great at something just to do it, you could try new things too.
