Answer:
0.3 Btu/(h ft °F) = 0.5189 W/(m°C)
105 Btu/(h ft² °F) = 596.2215 W/(m²°C)
Explanation:
<u>Thermal conductivity of a substance is defined as the measure of the tendency of the substance to conduct heat.</u>
<u>The SI unit of thermal conductivity is W.m⁻¹K⁻¹ .</u>
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,
<u>0.3 Btu/(h ft °F) = 0.5189 W/(m°C)</u>
<u>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.</u>
<u>The SI unit of thermal conductivity is W.m⁻²K⁻¹ .</u>
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,
<u>105 Btu/(h ft² °F) = 596.2215 W/(m²°C)</u>
