Answer:
Concentration factor will be 1.2
So option (C) will be correct answer
Explanation:
We have given outer diameter D = 1.25 in
And inner diameter d = 1 in and fillet ratio r = 0.2 in
So 
ratio will be 
And 
ratio will be 
Now from the graph in shaft vs torsion the value of concentration factor will be 1.2
So concentration factor will be 1.2
So option (C) will be correct answer.

(NH4)2Cr2O7→Cr2O3+N2+4H2O
Answer:
(a). max possible efficiency = 55.62%
(b). max power output = = 133.5 MW
Explanation:
From the question we were given the Maximum temperature in the system as
Tmax = 500°C
Minimum temperature in the system Tmin = 70°C
the Heat supplied to the boiler Qb = 240000 KJ/s
we use the temperature conversion factor from °C to K
given T(K) = T (°C) + 273
⇒ Tmax = 500 + 273 = 773 K
⇒ Tmin = 70 + 273 = 343 K
(a). we are to determine the maximum possible thermal efficiency;
(Πth)max = 1 - Tmin/Tmax
(Πth)max = 1 - 343/773 = 0.5562
(Πth)max = 55.62%
(b). to determine the maximum possible power output for the plant we have;
(Πth)max = Wmax/Qb
where Wmax rep the maximum power output
(Πth)max = 0.5562
Qb = 240000
∴ Wmax = 0.5562 × 240000 = 133505.6 Kw
Wmax = 133.5 MW

Explanation:
Your car's owner's manual will provide a maintenance schedule designed to keep your brakes in good condition. Following it is the easiest way to avoid expense repairs and the potential for catastrophic brake failure. But at the very least, you should have your brakes inspected every year.
