Amount of water that a steam engine would take to evaporate in
Answer to Problem 107A
Explanation of Solution
Given:
Time elapsed,
Power produced,
Efficiency of engine is
Formula Used:
Where, Pis power, W is work and tis time.
Calculation:
Power can be given as,
Where, P stands power, W for work and t for time.
Therefore
If the engine is supposed to be only 20 percent efficient, then it must use five times more heat to produce the 1000J/s.
Where,
Thus,
Conclusion:Hence, a steam engine would evaporate
