Copper losses are also referred to as I^2 R losses. Copper loss is due to heating due to the current passing through the copper windings.
Copper is not something that is calculated. The amount of copper might be, or copper losses / load losses, might be, but "copper" is not calculated.

'Copper loss' (I2R losses) is the generic term to describe energy losses that occur in any conductor (windings, in the case of transformers and other machines). The term applies, even when the conductors are manufactured from aluminium or other metals. The losses occur due to the temperature difference beween the conductor and the surrounds, causing heat transfer away from the conductor.
how to reduce copper losses in a transformer Copper losses are due to the resistance of the copper (or aluminum) windings. To reduce copper losses the transformer would have to be rewound with heavier gage wire.
Friction in the bearings and in the commutator, and windage loss. Electrical resistance of the armature and field windings and the brushes.
copper losses are power losses due to flow of current in the wires or resistances,if the resistance is R, current is I then copper losses are I2R. for a 3-phase system; copper losses are same but for a single line, total losses are 3I2R.
Friction and windage causes mechanical loss in DC machines.
Yes, the output line used to find the losses, usually for smaller machines we take copper losses equal to the iron losses.
All DC machines are works based on the principle of FARADAY'S LAW OF ELECTROMAGNETIC INDUCTION.
