Table 121 Gives The Seireg And Dandage Curve Fit

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?
