A piece of corroded metal alloy plate was found in a submerged ocean vessel. It was estimated that the original area of the plat

e was 750 in 2 and that approximately 8.2 kg had corroded away during the submersion. Assuming a corrosion penetration rate of 4 mm/yr for this alloy in seawater, estimate the time of submersion in years. The density of the alloy is 4.5 g/cm^3.

Answer:

The time of submersion is 0.94 years

Explanation:

Using the equation

CPR = KW/ρAt

in terms of t we have

t = KW/ρA(CPR)

750in^{2} = 4838cm^{2}

t = 87.6 * (8.2*10^{6})/4.5*4838*4

t = 8248 hours

convert to years

t = 8248/8760 = 0.94 years

Elodia [21]

Answer:

annual payment  =  $40000

Explanation:

given data

annual compound interest = 4%

fund value = $1,000,000

to find out

annual payment

solution

we get here annual payment  that is express as

annual payment  = fund value × annual compound interest  ..................1

put here value we get

annual payment  =  4%  × $1,000,000

annual payment  = 0.04 × $1,000,000  

annual payment  =  $40000

Steam enters a heavily insulated throttling valve at 11 MPa, 600°C and exits at 5.5 MPa. Determine the final temperature of the
7nadin3 [17]

Answer: the final temperature of the steam 581.5 °C

Explanation:

Given that;

P₁ = 11 MPa

T₁ = 600°C

exit at; P₂= 5.5 MPa

Now from superheated steam table( p=11 MPa, T=600°C)

h₁ = 3615 kJ/kg  

h₁ = h₂ ( by throttling process and adiabatic isentholpic )

from saturated steam table at; ( h= 3615 kJ/kg, P= 5.5 MPa )

Temperature = 581.5 °C

Therefore the final temperature of the steam 581.5 °C
