Is the pi group 4 already an acceptable form or answer or do you always have to modify it into the Reynold's number?

which yields
II4:
II4
ph² √√g
We recognize this II as the inverse of a kind of Reynolds number. We also split the h terms to separate them into a length
scale and (when combined with g) a velocity scale. The final form is
ph√√gh
Modified II₁ = a Reynolds number:
II₂
μl
