An engineer who is working on the heat transfer analysis of a house in English units needs the convection heat transfer coefficient on the outer surface of the house. But the only value he can find from his handbooks is 22 W/m2·K, which is in SI units. The engineer does not have a direct conversion factor between the two unit systems for the convection heat transfer coefficient. Using the conversion factors between W and Btu/h, m and ft, and °C and °F, express the given convection heat transfer coefficient in Btu/h·ft2·°F.

Question

An engineer who is working on the heat transfer
analysis of a house in English units needs the convection
heat transfer coefficient on the outer surface of the house.
But the only value he can find from his handbooks is
22 W/m2·K, which is in SI units. The engineer does not have
a direct conversion factor between the two unit systems for
the convection heat transfer coefficient. Using the conversion
factors between W and Btu/h, m and ft, and °C and °F,
express the given convection heat transfer coefficient in
Btu/h·ft2·°F.
