9 Problem 1 (35 points): Two metallic cylinders (diameter 0.2m, thermal conductivity 150W/m.K, density 8500kg/m', and heat capacity = 650J/kg.K] initially at a temperature of 600K. Suddenly, the first cylinder is placed in a fluid having a temperature of 50C with a heat transfer coefficient of 10W/m.K., and the second cylinder is placed in another fluid also at a temperature of 50C, but with a heat transfer coefficient of 450W/m.K. How long will it take each cylinder so that the temperature at a distance of 3cm from the surface reaches 350K. conditions stroke a Connection E.c
