A power supply consists of three rectifiers in series. Each rectifier has a Weibull failure distribution with β equal to 2.1. However, they have different characteristic lifetimes given by 12,000 hr, 18,500 hr, and 21,500 hr. Find the MTTF and the design life of the power supply corresponding to a reliability of 0.90. After you calculate both values add them together and provide it as your answer to this problem. (two decimals)

Re-derive an expression for average NuL (= hLL/k) for flow over a flat plate by integrating the expression for average hL for a mixed BL. For Rex,cr, use 123456 (keeping the same sequence), and find the constant B (in Eq. 7.38). Also show that for Rex,cr = 500,000, B is indeed equal to 871. eq. 7.38=> NuL=(0.037 ReL^(4/5)-B)Pr^(1/3) 0.6<=Pr<=60 Rex,c <= ReL <=108
