What is the best angle for an air propeller?
The best "angle of attack" for a propeller depends on many factors, the main ones being: the speed of airflow over the blade; the distance along the blade from the centre of revolution; the physical dimensions of the blade; the density of the air which it is trying to pull, or to push, to produce the force called "thrust" which drives the blade, and the aircraft attached to it, through the air. That is why the blade does not have a simple flat surface, but one which has many angles of attack along the blade due to the complicated shape of the blade.
When an air molecule bounces off an object it?
whe a air molecule bounces of and object it puts force in to the object that it bounce of
What simple machine on blade of electric fan?
fan blades are inclined to an angle of less than 90 degrees. When a fan motor turns the blades, the blades move through the air at an incline; the inclined surface passing through the air pushes the air forward, as the air is scooped up by the leading edge of the fan blade and set in motion as it passes over the surface.
What are the four elemants?
water,earth,fire,air
What is a four lettered word for moving air?
wind
Does a 5-blade ceiling fan provide more air movement than a 3-blade fan?
This would generally depend on the size of the fan blades in question as well as the rating of the fan motor. 3 large blades can move as much air as four or five smaller blades. The question is similar to asking, is a big car faster than a small car.
Why does air conditioning use more fuel?
Because the air conditioning compressor, is run from a pulley off of the engine. This puts an additional load on the engine, which causes more fuel to be used.
How fast would a helicopter blade need to be to catch the air on fire?
Since air is not inherently flammable, there is no speed at which a helicopter blade would catch the air on fire.
Why does warm air hold more water vapor then cold air?
Because Water vapor is why the air is warm More specifically the Evaporation/precipitation cycle puts heat into the air via water vapor carrying heat from the surface of the earth into the air If the Surface is hotter then more evaporation happens and in turn more heat gets into the air with the associated humidity
What is an air column?
the weight of a column of air above you that puts pressure on you
What do you call a pump that puts air into car tires?
An air compressor

How do you use storm blade in Dragonica?
To use storm blade in Dragonica online is to first launch your monster(s)in the air then after that quickly use storm blade and there you go you did storm blade
Does a changed filter help the air conditioner?
A clean filter puts less strain on the a/c, helping it to run more efficiently.
How does air pressure cause the motion of a sailboat?
it puts more weight in the sailboat and makes it have momentum and moves the wind so it can move
What is the cellular process that puts carbon into the air?
photosynthesis
Why do helicopters have a difficult time flying at altitudes above 6000 m?
A helicopter blade works the same way as a wing on a fixed wing aircraft. The air flowing faster over the top of the airfoil generates lift. When a helicopter flies at a high altitude the air gets thinner. Because the air is thinner, more pitch on the blades is needed to keep the helicopter in the air. When too much pitch is on the blades the blades stall, air moves past the bottom of the blade and creates a vortex behind the top of the blade. All lift is lost and you lose altitude.
