it is ratio of the total heat transfer from the surface area associated with both the fins and exposed portion of the base to maximum heat transfer from same surface area
(in ideal conditions we get maximum heat transfer)

How is condenser high efficiency obtained?
the high efficiency is obtained by using a larger condenser surface or by using more mordern alloys with more extended surface or fins
Why car radiator is design with thin fins and black in colour?
Car radiators have fins to allow the flow of air to enter, but as well as having a bit of protection. If it didn't, you would have a car with a hole in the front. Also, they are black to absorb and radiate heat. Black bodies radiate heat better so that is why they are black. The thin fins improve the overall surface area so that heat is dissipitated to the ambient efficiently. Hope this helps.
What are some examples of bioengineering?
adaptive bioengineering is using examples from nature and adapting them to human use, such as whales have grooves in their fins which decrease co-efficient drag and use this on wind turbines to increase efficiency
If a ramp were coated with a smoother surface the ramp and efficiency would .?
The smoother the surface of a ramp, the greater is the danger of a vehicle slipping and losing traction.A wet, smooth ramp could cause a pedestrian to slip over and be hurt.
Why do you use fins and cone for a bottle rocket?
You use fins and a nose cone on a bottle rocket because the cone reduces the drag on the rocket, and the fins help stabilize the rocket.
How is condenser high efficiency obtained?
the high efficiency is obtained by using a larger condenser surface or by using more mordern alloys with more extended surface or fins
What is in Cooling Fins on A Radiator?
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
What effect will bent cooling fins on the condenser have on the refrigerant system?
Efficiency drops dramatically depending on how badly bent the fins are.
How many fin's should a rocket have?
It depends on a lot of stuffs like how much do you want your rocket to be stabile. But at least it must be 3. For example for the same stability you may have 3 fins that have large surface area or 4 which is smaller or more. When you increase the number of fins with the same surface area then the drag will increase because of the surface friction so 3 or 4 fins are generally used but there is no certain limit of the number of fins .
Why fins are provided on heat transferring surfaces?
Using fins increases the surface area of the cover plate and more is the surface area meaning more place for heat dissipation or heat exchange. In simple words it multiplies the cooling effect.
Which component has the highest overall efficiency at a power plant?
generator
What reduces the overall efficiency of respiration?
bad things in the air
What does efficiency mean in economics?
In economics, efficiency means the overall use of resources. The overall use of resources can help maximize the production of the goods. In turn, the potential to make more money is there.
If efficiency of converting chemical to thermal energy was 90 percent what would the overall efficiency be?
In saying what the overall efficiency would be, I suppose you mean for other processes, creating the chemical energy for example, and using the thermal energy. This is impossible to answer, not knowing what these processes are.
Is it better to wakeboard with fins or without?
Having fins will give you more control. Without fins you will be able to do surface 180's easier and landing tricks will be a little more forgiving.
Why are fins are attached to the pipes inside the heater?
to increase surface area
Why is the economizer constructed with fins?
Fins are a relatively easy and inexpensive way to increase the heating surface of an economizer. By utilizing fins it is possible to reduce the economizer footprint while achieving the desired performance.
