Homework Help: Solar Neutrino Flux

  1. Aug 13, 2014 #1
    1. The problem statement, all variables and given/known data

    Hello Guys :)
    I have been studying neutrinos this term in physics and have been trying to calculate the neutrino flux on earth. I have found an equation but I am just unsure about what the variables in the equation stand for.

    2. Relevant equations

    F = N/(A t) = E/(A t) × N/E

    3. The attempt at a solution

    I know that F is the neutrino flux, but I am just unsure of what the other ones stand for. Is this the right formula or is there a formula that is better or easier to understand?

    Thank you!

    Well, this is a general formula for any flux essentially. N is the number of of neutrinos produced, A is the area they are (evenly) spread over, and t is the time they were produced in. In the second step, the total energy R has been introduced. The first factor is then the energy flux, E/t is the power of the Sun into neutrinos and the second factor is the reciprocal of E/N, the energy per neutrino.
