Engineering
1 answer:
svlad2 [7]3 years ago

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 :)

A program is seeded with 30 faults. During testing, 21 faults are detected, 15 of which are seeded faults and 6 of which are ind
Vesna [10]

Answer:

Estimated number of indigenous faults remaining undetected is 6

Explanation:

The maximum likelihood estimate of indigenous faults is given by,

N_F=n_F\times \frac{N_S}{n_S} here,

n_F = the number of unseeded faults = 6

N_S = number of seeded faults = 30

n_s = number of seeded faults found = 15

So NF will be calculated as,

N_F=6\times \frac{30}{15}=12

And the estimate of faults remaining is  N_F-n_F = 12 - 6 = 6

Refrigerant-134a is throttled from the saturated liquid state at 800 kPa to a pressure of 140 kPa. Determine the temperature dro
zavuch27 [327]

Answer:

The temperature drop is 61.1 °C

The final specific volume of the refrigerant is 1.236 m^3/kg

Explanation:

Initial pressure of refrigerant = 800 kPa = 800/100 = 8 bar

Final pressure of refrigerant = 140 kPa = 140/100 = 1.4 bar

From steam table

At 8 bar, initial saturated temperature is 170.4 °C

At 1.4 bar, final saturated temperature is 109.3 °C

Temperature drop = initial saturated temperature - final saturated temperature = 170.4 - 109.3 = 61.1 °C

Also, from steam table

At 1.4 bar, specific volume is 1.236 m^3/kg

Final specific volume of the refrigerant is 1.236 m^3/kg
