A cubic machine tool with a dimension of 25 mm * 25 mm 25 mm has an initial temperature of 589 K and exposed to a convection environment at 301 K. After 3,4 minutes later, the temperature of the tool is measured as 416 K. Assume that the lumped system analysis is applicable, calculate the heat transfer coefficient of the convection environment. Properties of machine tool: Density, p=8.881 kg/m3 Specific heat, C=381 J/(kgK) Thermal conductivity, k=394 W/(mK)
