The relative efficiency of jet propulsion decreases further as animal size increases.
If part of the discharge race is sucked back into the propeller, efficiency decreases sharply.
From this equation it is apparent, however, that as the quasi-phase match order increases, the efficiency decreases by .
When the plants were exposed to short-wavelength light, (less than 660 nm), the efficiency also decreased.
You are correct in that the efficiency decreases with increasing temperature.
At around six years of age, the koala's chewing teeth begin to wear down and their chewing efficiency decreases.
When also producing heat for district heating the electrical efficiency decreases, as the heat exchange is carried out at a higher temperature.
Since temperature inversions create stable, stratified conditions, the efficiency of that heat transport decreases.
The efficiency of such systems has decreased service times and increased efficiency of orders.
But at some point the returns to investment in labour will start to diminish and efficiency will decrease.
