How do I account for torque and loss in a 2D motor model?

For a 2D model, the total loss is given in W/m and torque in N*m per m. As the result is assumed to be continuous in the direction perpendicular to the two-dimensional model, the total loss in W or the total torque N*m is obtained by multiplying the loss in W/m or the torque in N*m per m by the motor's length in metres.
