Answer:
final temperature T = 24.84ºC
Explanation:
given data
copper volume = 1 L
temperature t1 = 500ºC
oil volume = 200 L
temperature t2 = 20ºC
solution
Density of copper 
cu = 8940 Kg/m³
Density of light oil oil = 889 Kg/m³
Specific heat capacity of copper Cv = 0.384 KJ/Kg.K
Specific heat capacity of light oil Cv = 1.880 KJ/kg.K
so fist we get here mass of oil and copper that is
mass = density × volume ................1
mass of copper = 8940 × 1 × 
= 8.94 kg
mass of oil = 889 × 200 × = 177.8 kg
so we apply here now energy balance equation that is
= 0
put here value and we get T2
= 0
solve it we get
T = 24.84ºC
Answer:
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.
Hope that help :)
