Short answer, total static pressure in the HVAC community includes dynamic losses from fittings and is equal to total pressure. Losses from fittings (elbows, branches, tees) is sometimes converted to an equivalent length of "straight duct" and then applied a friction loss. This might be why there is the misnomer of total "static" pressure. Or the loss coefficient ("C") for a fitting is looked up in a table and multiplied by velocity pressure ("Vp") to determine the loss.
The total pressure includes external static pressure and internal static pressure. External static pressure includes losses from volume control dampers, fire dampers, air outlets, duct length pressure drop (i.e. friction losses), duct fittings (i.e. dynamic/velocity losses), louvers, etc.
Internal static pressure includes things like filters, cooling coils, heating cools, and heat exchangers.
So, you should use the "total" pressure in your numbers below, as it includes the dynamic/velocity pressure loss from fittings.
