The future perfect tense forms are made by putting ‘will / shall + have’ before the past participle from the verb. these sentences can be changed into the passive if the active verb has an object
i hope this helps :D thanks
Answer:
451 kj/kg
Explanation:
Velocity = 139m/s
Temperature = 70⁰C
T = 343K
M1 = v/√prt
= 130/√1.4x287x343
= 130/√137817.4
= 130/371.2
= 0.350
T1/To1 = 0.9760
From here we cross multiply and then make To1 the subject of the formula
To1 = T1/0.9760
To1 = 343/0.9760
To1 = 351.43
Then we go to the rayleigh table
At m = 0.35
To1/To* = 0.4389
To* = 351.43/0.4389
= 800k
M2 = 1
Maximum amount of heat
1.005(800-351.43)
= 450.8kj/kg
= 452kj/kg
The acquisition of additional certifications with a personal refined craft skills can increase the odds for career advancemen.

Answer:
A) ν = 0.292
B) ν = 0.381
Explanation:
Poisson's ratio = - (Strain in the direction of the load)/(strain in the direction at right angle to the load)
In axial tension, the direction of the load is in the length's direction and the direction at right angle to the load is the side length
Strain = change in length/original length = (Δy)/y or (Δx)/x or (ΔL/L)
A) Strain in the direction of the load = (2.49946 - 2.5)/2.5 = - 0.000216
Strain in the direction at right angle to the load = (7.20532 - 7.2)/7.2 = 0.0007389
Poisson's ratio = - (-0.000216)/(0.0007389) = 0.292
B) Strain in the direction of the load = (2.09929 - 2.1)/2.1 = - 0.0003381
Strain in the direction at right angle to the load = (5.30470 - 5.3)/5.3 = 0.0008868
Poisson's ratio = - (-0.0003381)/(0.0008868) = 0.381

Explanation:
600 megawatts =
568 690.272 btu / second
thermal eficiency=work done/Heat supllied
0.38=568690.272/Heat supplied
Heat supplied=1496553.35btu /s
heat emmitted to the atmosphere=heat supplied -work done=(1496553.35-568690.272)=927863.1 btu/s
feed rate=(1496553.35)/12000=124.71 lb/s =10775184.1056 lb/day=5 387.472 ton / day
sulphur content released=(0.03*124.71)/(1.496553)=2.5 lb SO2/million Btu of heat input
so
the degree (%) of sulfur dioxide control needed to meet an emission standard=(2.5/0.15)*100=1666.67 %
the CO2 emission rate=220*(1.496553) =329.241 lb/s =12 903.0802 metric ton / day
