Hydraulic Institute launches viscosity correction standard
By eliminating the need for interpolating graphic solutions, this standard has major technical significance and practical applications, says Gregg Romanyshyn, HIs technical director. This landmark standard will provide valuable guidance to pump manufacturers, users, and others who have an interest in the performance of rotodynamic pumps.
HI members developed the new standard along with representatives from France, Germany, Italy, Japan, and Switzerland. It also includes contributions from industry experts and veterans.
The standard covers conventional rotodynamic pumps, including open or closed impellers and single or double suction pumps. It further contains information on methodology, definitions of symbols and terms, flowcharts that outline the procedure, theoretical explanations behind the methodology, and a method for estimating net positive suction head required (NPSHR).
