I cannot think of many disadvantages aside from cost. The advantages however are numerous.
Better fuel economy, faster speed, better control are a few of the biggest.
It presents a low surface area to the direction of travel through streamlining.
An advantage of using a barometer is that you can measure air pressure.
By streamlining an object you are reducing the drag caused by the medium that the obect is travelling through.i.e. making a car more streamlined reduces the drag caused by the air as it moves through it.Drag can otherwise be called resistance; e.g. wind resistance.
It reduces friction (air or water).
Air Resistance is a force.
air resistance
to reduce air resistance or drag.
The streamlining shape.
Force streamlining reduces air resistance or air friction.
It tends to reduce air (or water) resistance.
In believing in god, one can understand everything.
streamlining is the process by which the designs of moving tools like cars are made easy for the air to flow, to avoid air resistance or friction.
It presents a low surface area to the direction of travel through streamlining.
Some advantages to an air cooler include:Cooler temperaturesComfortSome disadvantages to an air cooler include: Uses electricityNoise pollutionBigger expenseTakes up space
Wind tunnels are used to improve the streamlining of cars.The shape of a car can be made like a tear-drop or like an aeroplane wing to reduce air resistance. Sometimes a spoiler is fitted at the the back to improve the air flow making it more streamlined. Another way to reduce air resistance is to make the car closer to the ground.
