Gas turbines extract the energy from combustion gas
and heat engines convert thermal and chemical energy to mechanical energy
gas is considered a chemical so i'm pretty sure it is considered one
Answer:
C. Brainstorm
Explanation:
<em>Brainstorming refers to thinking and developing ideas and solutions to problems</em>. It involves a free-thinking approach and putting oneself in the context of the problem you are attempting to solve. You can use the empathy maps to combine ideas from interviewing other people on the same. This stage is followed by defining the problem, concept generation, developing a solution, constructing a testing a prototype, evaluating the solution and finally presenting the solution.
Answer choice A is incorrect because it is the last stage .
Answer choice B is incorrect because it is the second stage.
Answer choice D is incorrect because it is step 5 and 6.
Answer:
Automation generally means “a process performed without human assistance”, while autonomy implies “satisfactory performance under significant uncertainties in the environment and the ability to compensate for system failures without external intervention [emphasis mine].”

Answer:
A) m' = 351.49 kg/s
B) m'= 1036.91 kg/s
Explanation:
We are given;
Pressure Ratio;r_p = 12
Inlet temperature of compressor;T1 = 300 K
Inlet temperature of turbine;T3 = 1000 K
cp = 1.005 kJ/kg·K
k = 1.4
Net power output; W' = 70 MW = 70000 KW
A) Now, the formula for the mass flow rate using the total power output of the compressor and turbine is given as;
m' = W'/[cp(T3(1 - r_p^(-(k - 1)/k)) - T1(r_p^((k - 1)/k))
At, 100% efficiency, plugging in the relevant values, we have;
m' = 70000/(1.005(1000(1 - 12^(-(1.4 - 1)/1.4)) - 300(12^((1.4 - 1)/1.4)))
m' = 70000/199.1508
m' = 351.49 kg/s
B) At 85% efficiency, the formula will now be;
m' = W'/[cp(ηT3(1 - r_p^(-(k - 1)/k)) - (T1/η) (r_p^((k - 1)/k))
Where η is efficiency = 0.85
Thus;
m' = 70000/(1.005(0.85*1000(1 - 12^(-(1.4 - 1)/1.4)) - (300/0.85)(12^((1.4 - 1)/1.4)))
m' = 70000/(1.005*(432.09129 - 364.9189)
m'= 1036.91 kg/s
