Q. Is the upper heating value and higher heating value the same thing?
Q. What is specific entropy? Please explain simply and use an analogy.
Q. What does 150% theoretical air mean in air-fuel mixture ratios for fuels? Is it different from normal air?
Q. I know that the entropy generation (Sg) equation is:
Sg = (m3 s3) - (m1 s1) - (m2 s2) + [Q out / T0]
(M3 = Outlet mass flow rate, S3 = outlet entropy, T0 = temperature)
Then, is the rate of entropy production equation different? Can it be derived from this equation? If it's different, why? Is it so?
Please write the equation!
