119. A few words may be said as to the calculation of the slip, 

 which is here expressed in p. p. s., and the calculation of the torque. 



120. Slip. The slip can easily be found with the help of formula 

 (15), as all quantities, with the exception of ~2 are known. 



121. Torque. The torque in synchronous watts is then obtained by 

 multiplying the output in watts by the ratio of ~i -f- ~.
