Abstract : It was proposed in previously published work that the effect of the properties of a liquid on cavitation phenomena can be evaluated in terms of the number 'B', which is the ratio of the volume of vapor formed during cavitation to the volume of the liquid flow. The experiments described in the article were carried out in a Venturi cavitation tube. The temperature of the water was varied from 290 to 359K, and the temperature of the alcohol from 293 to 332K. The calculations show that, with these changes in temperature, the B number changes 30 times for water and approximately 4 times for alcohol. The article includes a sketch of the cavitation tube.
