What elevations shall I put in the energy equation....?

... to get the total discharge head (TDH) of a pump? I mean, let say that my pump is higher than the end of the pipeline, and there are soe places lower than the end of the pipeline. Do I have to take both elevations (Z1 and Z2)as the lower and higher point in the pipeline in question? Or, what I have to do is, just, take the beginning and the end of the pipeline for Z1 and Z2 elevations? This is the formula: Z1+P1/ghama+v^2/2g+Hp=Z2+P2/ghama+v^2/2g+Hm+Hf where "Z1" and "Z2" are elevations, "ghama" is the water density, "g" is the gravity acceleration, "Hm" is the minor losses, "Hf" is the friction losses, "P1" and "P2" are the pressures, and "V1" and "V2" are the water velocity.

Also, do anyone knows what is the kinematic viscosity of the sanitary water? I wander if it's the same as the water kinematic viscosity.
