If a leaf is to maintain a temperature of 40.0°C , it must lose 253 W/m2 by transpiration (evaporative heat loss). Note that the leaf also loses heat by radiation, but we will ignore this. How much water is lost after 1.00 h through transpiration only? The area of the leaf is 0.00800 m2. Heat of vaporization for water is 2256 kJ/kg (see Table B.5).

Consider a 20 cm thick granite wall with a thermal conductivity of 2.79 W/m·K. The temperature of the left surface is held constant at 50°C, whereas the right face is exposed to a flow of 22°C air with a convection heat transfer coefficient of 15 W/m2·K. Neglecting heat transfer by radiation, find the right wall surface temperature and the heat flux through the wall.
