An interpolating equation for the dynamic viscosity of water substance is presented which is in good agreement with the experimental viscosity data in a large range of temperatures and pressures. The equation contains a smaller number of coefficients than the current international equation for the ...
The viscosity of water at a temperature of 20 degrees Celsius is approximately 0.01 poise or 10-3 Pa.s (Pascal seconds). Viscosity is a measure of the resistance of a fluid to deformation at a given rate.
The results show that a gel-like structure requires higher pressure for the cavitation to grow, and both gel and water models exhibit strain rate effect on the cavitation threshold pressure. We have also found that the cavitation collapse time is dominated by the viscosity of the medium....

Dynamic viscosity h(Eta) is for most formulated products, unaffected by density, often measured with rotary instruments. It considers the product's rheological behavior, having an absolute nature. Units are Pa. s, mPa. s (where 1 mPa.s = 20 °C water viscosity), or Poise, cPoise. ...
After using formula (3) to figure outKs, use\({k}_{20}=\frac{{\eta }_{T}}{{\eta }_{20}}\)to calculateKSat standard temperature, where ηTis the dynamic viscosity coefficient of water at T °C and η20is the dynamic viscosity coefficient of water at 20 °C. ...
The friction velocity is defined as follows [29]:(16)⁎u⁎=τsρ where τs is the shear stress of the fluid over a surface S [Pa]:(17)τs=μ∂ut∂n|S with μ the laminar dynamic viscosity of the mixture [Pa.s] and ∂ut∂n|s the surface tangential velocity normal gra...
ACCURATE values for the viscosity of water at various temperatures and pressures are necessary both to the chemist, who may require to relate viscosity with other phenomena, such as electrical conduction in aqueous solutions, and to the engineer, who may
