Designing a venturi?
Hi all -
is there somewhere with information on the design of a venturi to produce suction or vacuum ? We're trying to make a vacuum cleaner using compressed air and a coaxial venturi and figuring out how big to make the parts and what size ratio gives the best suction is turning out to be a problem. A google turns up tons of venturi information but I couldn't find a design formula relating orifice size, main tube size and restriction size along with inlet pressure or flow rate. Any pointers would be helpful... Thanks in advance Carla Skilled politicians, like high-end hookers, are only for those who can afford them. Michael Pearce |
