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.

Answer:
The final temperature is 26.96 F
Explanation:
Initial pressure = 30 lbf/in^2 = 30×1.01325/14.696 = 2.1 bar
Initial temperature = 20 F = (20 - 32)/1.8 + 273 = 266.33 K
From steam table, entropy at 2.1 bar = 7.111 kJ/kg.K
Initial enthalpy = 7.111×266.33 = 1893.9 kJ/kg
Final pressure = 60 lbf/in^2 = 60×1.01325/14.696 = 4.1 bar
From steam table, entropy at 4.1 bar = 6.889 kJ/kg.K
Work = 0.5 Btu = 0.5×1.05506 = 0.5908 kJ
Change in enthalpy (∆H) = work/mass
mass of refrigerant = 0.04 lb = 0.04×0.45359 = 0.0181 kg
∆H = 0.5908/0.0181 = 32.64 kJ/kg
H2 = H1 - ∆H = 1893.9 - 32.64 = 1861.26 kJ/kg
Final temperature = final enthalpy ÷ final entropy = 1861.26 kJ/kg ÷ 6.889 kJ/kg.K = 270.2 K = 1.8(270.2 - 273) + 32 = -5.04 + 32 = 26.96 F
Answer:
During film condensation on a vertical plate, heat flux at the top will be higher since the thickness of the film at the top, and thus its thermal resistance, is lower.

Answer:
Following are the solution to the given question:
Explanation:
The material is necessary to cook since frying is a speedy process for evaporation.
Drug A is now in the compressed fluid area, and the material would not boil if the pressure is chilled. Because the ship is solid, its substance A claim is false.
Unless the volume comprises of a drop in the heat, the B substance reaches a vapor pressure area and a wet region. That's the area that melting may occur. His claim for material B could therefore be true.
Answer:
The Border Patrol of the United States analyzes the purchase of a new helicopter for the aerial surveillance of the border of New Mexico and Texas with the Mexican Republic. 4 years ago a similar helicopter was purchased at a cost of $ 140,000.00. with an interest rate of 7% per year. Calculate the single payment factor and the present value factor with the above data with the table and formula. Draw the flow chart.
