Hi, Is there a way to calculate the velocity of air as it comes out from a nozzle? The nozzle is ejecting wind upwards and I would like to find the wind velocity with respect to the height. I currently have the pressure that is being supplied to the nozzle and also the nozzle diameter, is...

sorry for that miss understanding saying lol. When I introduced a feedback to the system by inserting a camera to give the actual position of the ball the servo motor will keep moving and as a result it keeps the ball oscillating and thus, the response is just plane oscillations without any...

Hi, I am trying to control the height of a ball in a jet stream of air. The height is being calculated by a camera and the air jet coming out controlled by a servo motor (connected with a butterfly valve). I found the open loop response by giving a step input, i.e I opened the value and...

Hi Berkeman My system is to control a valve which will allow an amount of volumetric air to pass through the pipe, so basically I am changing the pressure of air going out of the pipe. I am to suspend a ping pong ball by the jet stream of air and control its height by controlling the...

Equation for a vertical jet stream of air Homework Statement Got a small problem regards the Mathematical equation for a vertical jet stream of air. We all know that when air is coming out of a pipe it will create a pressure change, i.e the pressure will be lower at the center of the stream...

Control system for a jet stream of air Hi fellow engineers, I have a problem, how can I come out with a proper transfer function of a vertical jet stream of air coming out of a pipe to be able to use it in my design of a PID controller and Phase compensator ? The thing is that I have no...

Vertical jet stream of air Hi, Is there a way to find the transfer function of a vertical jet stream of air coming out of a pipe? The problem is that the stream of air is not inside a pre set volume, such as a wind tunnel. I don't thing that Bernoulli's equation is good since the pressure of...

Hi, First of all, Happy new year to you all, I hope you enjoyed it as much as I did :), but its back to work for me now :(. I am an electronics Student and doing a project about control systems to control a vertical jet stream of air coming out of a pipe. My basic setup is a motor that...

hi, I am an electronic engineer student and I am doing a study on control systems that can be used to control a ball's height in a vertical wind tunnel. I have a problem in calculating the fans needed (as in size and number of blades) and the amount of cfm that the fans need to produce...
