A long copper cylinder 0.6 m in diameter and initially at a uniform temperature of 38øC is placed in a water bath at 93øC. Assuming that the heat transfer coefficient between the copper and the water is 1248 W/(m2 K), calculate the time required to heat the center of the cylinder to 66øC. As a first approximation, neglect the temperature gradient within the cylinder r/h, then repeat your calculation without this simplifying assumption and compare your results.GIVENA long copper cylinder is placed in a water bathDiameter of cylinder (D) = 0.6 mInitial temperature (To) = 38øCWater bath temperature (T?^?) = 93øCThe heat transfer coefficient (hc ) = 1248 W/(m2 K)ASSUMPTIONSNeglect end effectsRadial conductiononly
