sure!
Initial data: force F we want to generate, hole diameter d (A is the corresponding area), air density rho
I can calculate the pressure delta_p (relative to atmosphere pressure) necessary to generate F:
delta_p = (2 * F) / (pi * d^2)
Then I can calculate flow velocity V:
V = sqrt (2 *...
i don't know the velocity, because i don't know which is the blower i will have.
i only know the force to get and the diameter of the hole (because I'm free to decide it).
can you write me the way you will follow to calculate pressure and flow rate?
thanks a lot for your help
the blower takes air from the atmosphere and put it outside through a tube (connected to the hole).
but the problem is that i need to choose the right blower to have the thrust of 35 N.
i have to define the pressure and the flow rate in order to choose the blower (i can choose the hole diameter...
Hello,
I have a box with a hole directly connected to a blower inside. I can use the air sent by the blower to give a thrust to the box, in order to move it. I can say the the box is in a room, so open air around the box.
The thrust should be 35 N and I have to calculate the pressure and the...
