Joukowski formula in rubber hose (water hammer)
Joukowski formula in rubber hose (water hammer)
(OP)
I would like to evaluate theoretically the pressure rise occuring during a water hammer effect in a piping circuit which includes high-pressure blended rubber hoses. Joukowski formula is based uppon Young modulus of the pipe material, but how to evaluate this variable with a composite "pipe"?
The hose is made of Vinyl/Buna-N mixture, and it is surrended by polyester and steel wire reinforcement... Moreover, rubber rigidity is normally dynamic dependent. How to evaluate water hammer effect in this condition?
