Using F=kQ1Q2/r^2, can anybody give a calculation for the h-bond between water molecules (partial positive hydrogen and partial negative oxygen)? I would like a link, anything, to find the values of Q1, Q2, and suggestions for approximating r.

It's partially a physics question: the formula I give is the general formula for calculating the force between two charges Coulomb's law.

It's for a physical chemistry experiment I devised which involves finding the temperature dependence of viscosity of water and using the chemistry/physics of hydrogen bonds to explain the phenomenon of viscosity's temp dependence.

What do you want it for?
Have a look at

If you want to keep it simple then according to wikipedia the length is 1.97 pm (1.97 Angstrom) and for oxygen charge = -2δ=-0.834 (since it forms 2 polar bonds) and for H +δ =+0.417 according to the model at
