Answer / manoj kumar

for single phase it is-
average voltage x average amp. x power factor (0.85)
____________________________________________________
1000
for three phase it is-

average voltage x average amp. x power factor (0.85) x 1.732
____________________________________________________________
1000

Answer / ram kumar pandey

For single phase
kW = V*I*cosQ/1000
For three phase
kW = 1.732*V*I*CosQ/1000

Answer / p l narayana

KW is an electrical specification that which intends the
amount of energy required to do a job
The given example will give an idea to calculate KW
10KG object is to move one meter distance in one
section then required kw is =weight*g*d/(t*1000) KW in
mechanical terms
Now in electrical terms
KW=V*I*PF
= 3^0.5*V*I*PF
WHERE V=Phase voltage
I=Phase current
PF=Power factor

Answer / arunkumar.s

Normally Voltage & Current Vil b Given,

Kw = V*i*Power Factor ( only Single Phase )

Kw = 1.73*V*I*Power factor ( only Three Phase )

Then, KVA vil b Given,

KW = KVA*Powerfactor ( Both single & Three Phase )

Answer / arun kumar.s

Voltage & Current vil b Given,

KW = (V*I*Powerfactor)/1000 ( only Single Phase )

KW = (1.732*V*I*Powerfactor)/1000 (Only Three phase )

KVA Vil b Given,

KW = KVA/Powerfactor (Both Single & Three Phase )

Answer / manik chatterjee

IN SINGLE PHASE,KW=V*I COS$
IN THREE PHASE,KW=1.732 *V*I COS$

Answer / e.subhash

KW = KVA X COS THETA

Answer / charlie

Kw=2*E*I*PF/1000
