Share capital refers to the total amount of capital raised by a company through the issuance of shares to its shareholders. It represents the actual amount of money invested by the shareholders in the company. On the other hand, nominal capital refers to the authorized capital of a company, which is the maximum amount of capital that a company is authorized to raise through the issuance of shares. It is the amount stated in the company's memorandum of association and represents the company's potential capital base. In summary, share capital is the actual amount of capital raised, while nominal capital is the maximum amount of capital authorized to be raised. **

Nominal groups are phrases that function as a single unit in a sentence and typically consist of a noun or pronoun along with any associated modifiers. These groups can serve as subjects, objects, or complements in a sentence. Nominal groups are essential components of sentences as they provide specific information about the subject or object being referred to. By analyzing nominal groups, we can gain a better understanding of the relationships between different elements in a sentence. **

Nominal expressions are linguistic constructions that function as nouns in a sentence. They can consist of single words or phrases that act as the subject, object, or complement of a sentence.

The nominal mass is the mass of an individual particle or molecule, typically expressed in atomic mass units (amu) for atoms and molecular mass units (amu) for molecules. It is the sum of the masses of the individual protons, neutrons, and electrons that make up the particle or molecule. The nominal mass is a useful concept in chemistry and physics for calculating and comparing the masses of different particles and molecules. **

To identify the nominal size and nominal pressure from a process diagram, you can look for symbols or labels that indicate the size and pressure of the equipment or piping. Typically, the nominal size is represented by a number that corresponds to the diameter of the pipe or equipment. The nominal pressure is usually indicated by a symbol or label that specifies the pressure rating of the equipment or piping. Additionally, you can refer to the legend or key of the process diagram for more information on the nominal size and pressure of the components. **

To identify the nominal size and nominal pressure based on the process diagram, you can look for symbols or labels that indicate the size and pressure of the equipment or piping. The nominal size is typically represented by a number that corresponds to the diameter of the pipe or equipment in millimeters or inches. The nominal pressure is often indicated by a symbol such as a number followed by "bar" or "psi" to represent the pressure rating of the equipment or piping. Additionally, you can refer to the legend or key of the process diagram for more information on the nominal size and pressure of the components. **
