Question 2 (10 points) A stainless-steel rod (p =7817 kg/mº, Cp = 460 J/kg. C, k= 35 W/m. C) of 6.4 mm in diameter (D) is initially at a uniform temperature T, of 25.C and is suddenly immersed in a liquid at T = 150°C with h = 120 W/m..C. Using the lumped- system method of analysis, calculate the time necessary for the rod temperature to reach 120°С. Take V/A.-D/4
