Answer:
protons and neutrons
Explanation:
An atom is said to be the simple units of matter and basic of describing elements structure. An atom of an element have protons , neutrons and electrons.
The protons and neutrons of an atom are usually located in the nucleus of an atom. The sum of the proton and neutron of an atom determines the atomic mass of an element. This means the proton and neutron plays a major role in determining the mass of an atom. The proton is usually positively charge and tends to repel each other in the nucleus of an atom. The neutron has no charge but usually possess more weight than the proton.
The electron is located at the outer parts of the atom. it usually revolve round the atom . The electron determines how the atoms of an elements bond with other atoms. For an electronic neutral charge of any atom the proton number is equal to the electron number.
The picture above illustrate how the proton, neutron and electron reside in the atom.

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.
