A dilute suspension of cyclohexane in distilled water at a temperature of 25°C flows in a smooth pipe with 5.25 cm inner diameter. The mean velocity is 2.5 m/s. Estimate the size of the cyclohexane particles in the pipe. The two phases are assumed to be mutually saturated, whereby
 where subscripts c and d represent the continuous and dispersed phases, respectively. For the distilled water– cyclohexane mixture, when the two phases are mutually saturated, the interfacial tension is
