Explanation:
Heat engine
Heat engine is a device which produce work while consuming some amount of energy .This engine works in cycle.In other words we can say that Heat engine is a device which covert thermal or chemical energy in to mechanical energy and after that this mechanical energy can be use for producing mechanical work.
Heat engine takes heat from high temperature and rejects heat to lower temperature and producing work.
We know that efficiency given as
From diagram we can say that
So efficiency
Answer:
62.5%
Explanation:
We are given that
A ten-station transfer machine has ideal cycle time=30 sec=
Frequency of line=0.075 stops per cycle
Average time=4 min
We have to determine the line efficiency
Line efficiency=62.5%
Hence, the line efficiency=62.5%
