Question 45
MENAT2 marksNeeds review
Ambient air flows over a heated slab having flat, top surface at
. The local temperature (in Kelvin) profile within the thermal boundary layer is given by
, where
is the distance measured from the slab surface in meter. If the thermal conductivity of air is 1.0 W/m.K and that of the slab is 100 W/m.K, then the magnitude of temperature gradient
within the slab at
is ____________ K/m (round off to the nearest integer).Log in to check the answer
