Max radius of falling liquid drop

[bengaltiger14]

The max radius a fallling liquid drop can have without breaking apart is given by the equation:

R=√(σ/gρ) where the rho is density of liquid (1000kg/m^3), and the surface tension is
.7275J/m^2. g is gravity

I am asked to determine the max radius of a drop in units of cm at 20 degrees celcius. Is this problem just a plug the values in problem and ignore the temperature? Is the temperature there just to throw me off?

The density σ does have a temperature dependence, but if the σ is a given with no reference to temperature in the problem, I'd have to wonder if the real problem is having you convert units correctly.

(Btw σ of water at 20 degrees is 0.9982071.)
