quizlet can help you its very helpful on quizes it some time mostly have the same excact quizes
Answer:
the estimated time of submersion is 17.7 years
Explanation:
Given the data in the question;
estimate the time of submersion in years.
we write down the relation between time of submersion and corrosion penetration as follows;
CPR(mpy) = K × W(mg) / [ A(in²) × p(g/cm³) × t(hr) ]
we solve for t
t = (K × W) / ( AP × CPR )
given that;
Area A = 5 in²
W = 2.3 kg = 2.3 × 10⁶ mg
density of steel p = 7.9 g/cm³
CPR = 200
we know that K is 534
so we substitute
t = (534 × 2.3 × 10⁶ mg) / ( 5 in² × 7.9 g/cm³ × 200 mpy )
t = 1,228,200,000 / 7900
t = 155468.3544 hr
t = 155468.3544 hr × ( 1 yrs / ( 365 × 24 hrs )
t = 17.7 years
Therefore, the estimated time of submersion is 17.7 years

Explanation:
The problem must be know before you can develop and solution, generate concepts, or construct and test a prototype
If you are struggling to attend the entirety of your online class, I would consider getting in touch with your teacher, telling your situation, and asking them to help you in whatever way possible. Many teachers may be willing to explain the contents of the lesson through email or office hours. A guidance counselor, if available, may also be willing to assist you by talking to teachers for you if they refuse to cooperate. It may also be helpful to talk to your parents and explain to them that you are worried about your grades declining if you are to continue studying from home. They may understand that while this alternative works for some, it does not benefit you.
