I have a 24 VDC solenoid (resistance 60 ohms, # turns = 2000).
How do I calculate the drop-out time and voltage?
there is a diode wired in paraell (Sp) to protect the supply circuit from the back-eMF. I believe that this slows the circuit down on drop-out but it does not slow it down enough...
I seen a design manual named "Aerospace Fluid Component Designer's Handbook" dating back to the 1960's. It was produced by the Air Force Rocket Propulsion Labratory.
Has anyone seen an updated version of this document?
If so where can I get one?
A simple vaccum can be made using compressed air though an orifice with an inlet placed just downstream of the orifice.
How do you calculate the pressure and flow through this venturi?
