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.
Answer:
D
Explanation:
The transcontinental railroad was worked on from both sides of America. At the Pacific Ocean and the Atlantic Ocean. The purpose was to make travel easier from one side of the country to the other, and to get American items to the east and west of America for export to other countries, as well as a few other reasons such as building up the interior of America.
Answer:
option(d)
Explanation:
The frequency of a wave is the property of the source of wave.
The velocity of all the electromagnetic waves is same as the speed of light. It only changes as the light passes through one medium to another.
The frequency is defined as the number of waves coming out from the source in 1 second.
As the frequency of wave increases, the number of wave coming per second increases.
So, the number of waves passing by increases but the speed remains same.
Option (d)
Answer:
Gamma rays
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
Explanation:
Given:
L = 1 mH = 
H
