Question 65
PINAT2 marksNeeds review
The left-hand side of a 20 cm thick wall is maintained at 25 °C. The right-hand side of the wall is exposed to hot air at 50 °C. There is no heat generation inside the wall and its thermal conductivity is 100 W/m·K. The convective heat transfer coefficient is 50 W/m²·K. Under steady state condition, the temperature (in °C) of the right-hand side surface of the wall is__________. (Rounded off to one decimal place)
