Abstract text:
In a laboratory facility with small orifices (d = 1.15...2.55 mm) there was found a maximum value for the flow coefficient (µ = 0.7) and the Re numbers which were obtained were determined by varying the viscosity of the liquid used, at which these values are reached: Re = 1,200 for alcohol, Re = = 3,700 for water.
Key Words:
small orifices; flow coefficient; the influence of viscosity.
