1. A mixture of 3 gases (A, B, and C) has a total pressure of 240kPa. If the partial pressure of Gas A is 107 kPa and the partial pressure of Gas B is 55 kPa, what is the partial pressure of
Gas C?

78 kPa

Explanation:

The total pressure is the sum of the partial pressures:

240 = Pa + Pb + Pc

240 = 107 + 55 + Pc

Pc = 78 kPa

78 kPa

Explanation:

Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing.

There are many abbreviations common to the vocabulary of people who work with engineering drawings in the manufacture and inspection of parts and assemblies.

Technical standards exist to provide glossaries of abbreviations, acronyms, and symbols that may be found on engineering drawings. Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, like BS8110 or Eurocode 2 as an example.
