Hello, in the question we have given that the output of an engine is 15 kilowatt and its mechanical efficiency.
00:08
So we have given the output, so that is nothing but the brake power.
00:16
So that is equals to 15 kilowatts is given, the mechanical efficiency, so eta is given that is equals to 85 percentage.
00:31
So that will be 0 .85.
00:34
So we have to calculate the indicated power.
00:38
So in the first part, we have to calculate the indicated power.
00:44
Now in order to find out the indicator power, indicated power, we'll use the efficiency formula.
00:50
So that is brake power divided by the indicated power.
00:54
So if i rearrange, i will get indicated power as equals to brake power divided by the efficiency.
01:00
So indicated power will be brake power is 15 kilowatt divided by this is 0 .85.
01:10
So if i calculate this, i will get this answer as 17.
01:18
So i will get, so it's 15 divided by 0 .85...
