Convert: thermal conductivity value of 0.3 btu/(h ft°f) to w/(m °c). surface heat transfer coefficient value of 105 btu/(h ft2 of) to w/(m20c)

0.3 Btu/(h ft °F) = 0.5189 W/(m°C)

105 Btu/(h ft² °F) = 596.2215 W/(m²°C)

Explanation:

Thermal conductivity of a substance is defined as the measure of the tendency of the substance to conduct heat.

The SI unit of thermal conductivity is W.m⁻¹K⁻¹ .

From the question , 0.3 Btu/(h ft °F) is to be converted to W/(m°C)

Thus,

1 Btu/(h ft °F) = 1.7296 W/(m°C)

So,

0.3 Btu/(h ft °F) = 1.7296×0.3 W/(m°C) = 0.5189 W/(m°C)

Thus,

0.3 Btu/(h ft °F) = 0.5189 W/(m°C)

Heat transfer coefficient is defined as proportionality constant between heat flux (Thermal power per unit area) and the temperature difference of the substance for that flow of heat.

The SI unit of thermal conductivity is W.m⁻²K⁻¹ .

From the question , 105 Btu/(h ft² °F) is to be converted to W/(m²°C)

Thus,

1 Btu/(h ft² °F) = 5.6783 W/(m²°C)

So,

105 Btu/(h ft² °F) = 5.6783×105 W/(m²°C) = 596.2215 W/(m²°C)

Thus,

105 Btu/(h ft² °F) = 596.2215 W/(m²°C)
