Question
A rectangular slab with surface area 2m? and with thickness 20mm is exposed to hot gas on one side. 30 W of heat is transferred from the hot gas to the slab surface while the temperature at the opposite side is measured as 85°C. Which of the following boundary conditions is true for 1D under steady-state condition: O a dT - K 30W/m2; T1-85°C dx Ob. hA(AT)= 30W/ m² ; T1=85°C h(AT)= 15W/ m² ; T1=85°C Od q=30W; T1=85°C;
