Explanation:
The volumetric flow rate of water will be as follows.
q = 
= 0.0378 
Diameter =
= 0.2032 m
Relation between area and diameter is as follows.
A =
=
= 0.785 x 0.2032 x 0.2032
= 0.0324
Also, q = A × V
or, V = 
= 
= 1.166 m/s
As, viscosity of water = 1 cP =
Pa-s
Density of water = 1000
Therefore, we will calculate Reynolds number as follows.
Reynolds number =
=
= 236931.2
Hence, the flow will be turbulent in nature.
Thus, we can conclude that the Reynolds number is 236931.2 and flow is turbulent.
The correct answer here is A - An atom with a positive charge has more
protons than electrons. In the other instances the atom would have a
negative charge.
Answer:
Potential energy is energy due to an object's height above the ground.
Potential energy = mass x gravity x height
Kinetic energy is energy due to the motion of the object.
Kinetic energy = 1/2 x mass x velocity²
It's A. volume
Pressure =

with const depends on the chosen unit of volume
I think so...
If its one significant figure, it means you round that number to the first digit for example 2457 to 1 significant figure will be 3000. Do you now how to round?
