Stand by Redundancy System resolution

[FVicente]

Dear colleagues,

I am trying to calculate the reliability of the system with two pumps, one is active and the other is in stand-by mode. The problem that i have is the system follows the weibull distribution, so i cant appliy the equation for a constant failure rate that appear in all reliability handbook.Unfortunately i havent found the equation solved for a Weibull distribution.

Someone has solved this equation?or if you have found in a book,please i need this mathematical formulation. I am attaching the equation that i have to solve

Best regards for all
