Question 814594: I have a table here for property values of gases.
At temperature 70C kinematic viscosity is 21.02 and at temperature 80C kinematic viscosity is 21.09 . How should i find the kinematic viscosity at 77C as kinematic viscosity values for that temperature is not given in the table
Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
Before calculators, we used to have to look everything up in tables.
cosine sine tangent and interpolate the quantities not listed
80-70=10
77-70=7
7 /10
21.09-21.02=.07
7/10*.07=.7*.07=.049
21.049 for 77 degrees
