Glycerine has a higher viscosity and a higher density than water. The higher viscosity (which is more significant) will tend to decrease Reynolds No whilst the higher density will tend to decrease it.

Since the diameter and flow rate is kept constant, the reynold number depends upon the coefficient of viscosity. I think water has more viscosity than liquid glycerine, so the reynold number would decrease. If I am wrong, then it is vice-versa.
