Power (single phase):P=Vp×Ip×cosφPower (3 phases):P= √3Vl×Il×cosφorP= √3Vp×Ip×cosφ Power factorPF= cosφ=R/(R2 + X2)1/2,φ= power factor angle. For the purely resistive circuit,PF= 1 (perfect). The apparent powerSis calculated according to Pythagoras, the active ...
Such independent knowledge on the elastic constants can be obtained, for instance, by ab initio calculations [2] and has recently become a routine activity [3]. For the calculation of phase and group velocities and the enhancement factor from elastic constants using the Christoffel equation, curren...
