To find a solution to this problem it is necessary to apply the concepts related to the Reynolds number and its definitions on the type of fluid.
A Reynolds number less than 2000 considers the laminar fluid, while a Reynolds number greater than 4000 is considered a turbulent fluid. (The intermediate between the two values would be a transient fluid)
The mathematical equation that defines the Reynolds number is given by

Where
Density
V= Velocity
D= Diameter
Viscosity
Our values are given as





The velocity can be find through the Discharge equation,
Q = VA
Where
V = Velocity
A = Area
Replacing,


Replacing at the Reynolds equation,



Since Reynolds' number is greater than 4000, then we consider this a turbulent fluid.

1.
A:Time (minutes)
B: Temp(degrees c)
2. Downward trend (temperature goes down as time goes on )
3.
A: not sure
B: temperature

5. Closes off any open airways
A sort of electricity is a light bulb or a phone / computer charger. plants food water. the sun and rain . that’s what i’m guessing!
0.0000004. since it is 10^-7 (note the negative), you would move thedecimal point 7 places to the left.
Answer:
B
Explanation:
Speed is the magnitude of the velocity vector, so it can never be negative.
