Flow and head with different viscocity than water
Flow and head with different viscocity than water
(OP)
In a old book named BOMBAS , "PUMPS" by Julio Hirschmann R. edited in Chile in year 1958 it have a chapter named
CALCS THE HEAD FOR WATER AND VISCOUS LIQUIDS
in spanish
CALCULO DE LA ALTURA DE ELEVACIÓN PARA AGUA Y LIQUIDOS VICOSOS
About it , it states that according to a article by Aisenstein , from USA : for a centrifugal pump the FLOW is invert rated to the viscocity raised to Y
and the HEAD is invert rated to the viscocity raised 2 times Y
reference MICHAEL D. AISENSTEIN ,
CHARACTERISTICS OF CENTRIFUGAL OIL PUMPS
9. PROCEEDINGS OF AMERICAN SOCIETY OF CIVIL ENGINEERS.
AUGUST 1928.
My question , there is any new approach about it ?
Or better how to get the new flow and head for any given fluid different from water.?

RE: Flow and head with different viscocity than water
There is 2 point of view:
1.Regarding a pump design , you should check h
This explain and calculate how capacity/head/efficiency changes its performance from water to viscous fluid.
2.Regarding a system design , It means "CALCS THE HEAD FOR WATER AND VISCOUS LIQUIDS IN PIPING SYSTEM". In this case, you could use this algorith: h
A VERY IMPORTANT NOTE IS THAT BOTH WEB REFERENCES A NEWTONIAN FLUIDS. FOR NON NEWTONIAN FLUID OTHERS ALGHORITMS MUST BE USED.
