Why is our blowing power so strong but sucking power weak, also same with leaf blowers and vacuum cleaners?
In: Physics
Blowing basically means you have an area of high pressure that is attempting to equalize with the environment pressure.
Sucking basically means you have an area of low pressure that is attempting to equalize with the environment pressure.
Assume the environment pressure is 1 atmosphere. Assume negative pressures are impossible.
Sucking can only give you a differential of 1 atmosphere… I.e. Vacuum versus the environment.
Blowing has no limit since you can have pressures of 3, 5, 10 or even 110 atmospheres of pressure versus the environment.
