A vapor bubble rises in a liquid. The relevant dimensional parameters are the liquid specific weight, ${}_l,$ the vapor specific weight, ${}_v,$ bubble velocity, $V,$ bubble diameter, $d,$ surface tension, $,$ and liquid viscosity, $.$ Find appropriate dimensionless parameters.

${}_1=\frac{{}_v}{{}_t},{}_2=\frac{{}_{t}d}{},$ and ${}_3=\frac{V}{}$

${}_1=\frac{{}_v}{{}_e},{}_2=\frac{r_e{d}_2^2}{},$ and ${}_3=\frac{V}{}$

${}_1=\frac{{}_v}{{}_e},{}_2=\frac{{}_{e}d}{},$ and ${}_3=\frac{d^{2}V}{}$

${}_1=\frac{{}_v}{r_e},{}_2=\frac{r_t{d}^2}{},$ and ${}_3=\frac{d^{2}V}{}$
