Temperature: Zeroth Law of Thermodynamics
Published in Kavati Venkateswarlu, Engineering Thermodynamics, 2020
The Rankine scale is related to Fahrenheit and as ΔT(R) = ΔT(°F) + 459.67 T(R)=350+459.67=809.67RT(R)=1.8T(K)⇒T(K)=T(R)1.8∴T(K)=809.671.8=449.82KT(°C)=T(K)−273.15=449.82−273.15=176.67°CAns.

The unit for temperature (t) measurement in the British gravitational system is the degree Rankine (°R). The Rankine scale is an absolute temperature scale. The degree Fahrenheit (°F) is commonly used and is related to the degree Rankine by t(°R)=t(°F)+460

The Celsius temperature scale, whose unit is denoted by °C, is defined by subtracting 273.15° from the Kelvin temperature scale. The triple point of water thus lies at exactly 0.01°C. The ice point is at approximately 0°C, and the steam point is at approximately 100°C. The Rankine scale (denoted by °R) is an absolute temperature scale whose degree is 1.8 times smaller than the Kelvin degree. It is thus defined by Eqs. 2.4 and 2.5 but with Am chosen such that Tm = 491.688°R at the triple point of water. The Fahrenheit temperature scale, whose unit is denoted by °F, is defined by subtracting 459.67° from the Rankine temperature scale.

Because there is a linear relationship between the temperature in the Rankine scale (absolute scale of thermodynamic temperature) and the double logarithmic of the viscosity, a linear model was developed for the viscosity of the bio-bitumen, as expressed in Equation 6. In this equation, Visco is the double logarithmic of the viscosity (cP), BHO is the bio-oil content (%), T is the temperature in the Rankine scale, and ai are statistically determined coefficients, with a R2 = 0.999, and included in Table 5.
