Consider a slab of 20 mm thickness. There is a uniform heat generation of q̇ = 100 MW/m³ inside the slab. The left and right faces of the slab are maintained at 150°C and 110°C respectively. The plate has a constant thermal conductivity of 200 W/(m.K). Considering a 1-D steady state heat conduction, the location of the maximum temperature from the left face will be at __________ mm.(answer in integer)
