In this question here we have given that n equals to 85 .71 % that is equals to 0 .8571.
00:15
Here f is given frequency that is 50 hz and p is given 4 and ns is equals to 120 f divided by p.
00:33
So here ns will come 1500 rpm.
00:41
Now here f is equals to 15 .7 kw that we can write as 15700 w.
00:55
Now stator loss is 889 w.
01:06
Now friction loss is 11000 w.
01:18
So here n equals to pout divided by p in.
01:26
So we can here p in is equals to p out divided by n.
01:35
So here p out is 15700 divided by n is 0 .8571.
01:48
So here when we calculate it we get p in is equals to 18317 .58 w.
01:59
Now here air gap power is that is pg is equals to p in minus stator loss.
02:17
So here p in is 18317 .58 minus 889.
02:28
So here when we calculate it we get pg is equals to 17428 .58.
02:38
Now mechanical power is pm equals to p shift plus rotational loss rotational loss...
