Table 121 gives the Seireg and Dandage curve fit for the absolute viscosity in customary U.S. engineering

Question:

Table 12–1 gives the Seireg and Dandage curve fit for the absolute viscosity in customary U.S. engineering units. Show that in SI units of mPa . s and a temperature of C degrees Celsius, the viscosity can be expressed as μ = 6.89(106) μ0 exp [(b/ (1.8C + 17))] Where μ0 and b are from Table 12–1 If the viscosity μ′0 is expressed in μreyn, then μ = 6.89μ′0exp [(b/ (1.8C + 127))] What is the viscosity of a grade 30 oil at 79◦C?
