![]() ![]() This differences are caused by the high concentrations of some type of ion species, such as (Na+: 7.7 g/l (#38T) Cl-1:7.7 g/l (#38T) SO4-2: 0.75 g/l (#68) S+: 0.24 g/l (#68) K+:0.15 g/l (# 27T) Ca+2: 0.074 g/l (#27T) B+:0.06 g/l (#38T) and Mg +2: 0.033 g/l (#38T)), in the geothermal fluids, which strongly effect on salt concentration dependence of the measured properties. The average differences between the measured geothermal fluids densities and viscosities and pure water values (IAPWS formulation) are within (0.1-1.77) % and (0.13-2.1) %, respectively, which are considerably higher than their experimental uncertainties. A sound-speed analyzer (Anton Paar DSA 5000) was used for simultaneously measurement of the speed of sound and density of the same geothermal fluid samples. The measurements were made using the Anton Paar DMA4500 densimeter and Stabinger SVM3000 viscodensimeter for four geothermal fluid samples from the various hot-wells Izberbas (No. Density, (ρ), speed of sound, (W), and viscosity, (η) of natural geothermal fluids from south Russia Geothermal Fields (Dagestan, Caspian seashore) have been measured over the temperature range from (277-353) K at atmospheric pressure. ![]()
