A solar collector receiving solar radiation at the rate of 0.5KW/m2 at temperature 80C and transforms it to a fluid within heat engine. The engine rejects energy as heat at temperature of 25C. The minimum collector area (in m2) if the plant produces 2KW of useful shaft power is
  • a)
    22
  • b)
    22.5
Correct answer is between '22,22.5'. Can you explain this answer?
Verified Answer
A solar collector receiving solar radiation at the rate of 0.5KW/m2 ...
Given, T2 = 25 +273 = 298 K, T1 = 80 + 273 = 353 K
Heat input to engine, Q1 = 0.5 KW/m2 = 0.5A KW
Where, A is the area of solar collector
For the minimum area A. collector the efficiency of heat engine would be maximum.
