Surface Tension of Oscillating Jets

A jet of an aqueous solution has a mean radius R of 0.2 cm and travels with a velocity V of 60 cm/sec. Density and viscosity may be taken as 1 glcrn and 1 cp, respectively. Calculate the surface tension using the simple and corrected Equations 5.100 and 5.101 if the wavelength A for an oscillation is 2.40 cm and if bIR is 0.25. 

Solving Equation 5.100 for y and substimting the above values, we find y = 32.9 mN/m. With Equation 5.101 the corresponding result is y = 34.8 mN/m. In this particular case the viscosity correction is negligible, so that the chief correction is for the finite amplitude.
