# Specific Energy Generation of the sun.

1. Sep 22, 2008

1. The problem statement, all variables and given/known data
(a) Compute the specific energy generation rate of the Sun as a whole.

(b) Assume a human of weight 100 kg has a “luminosity” of 100 W.
Compute the specific energy generation rate of a this human.

2. Relevant equations
Need help with the equations part.

3. The attempt at a solution
My first instinct was that the energy generation would just be the luminosity of the Sun, but this is a slightly more advanced astrophysics course in which I think they would be looking for something more. Does "specific energy generation rate" mean something more then just the rate it generates energy? Is there some equation I should have to solve these questions?

Thanks for the help!

Judging from the part (b), I'd guess that the specific energy generation means "Power generated per unit mass". So just take Sun's total luminosity and divide by it's total mass.
