Utilizing the viscosity () of water at 5, 20, 40, 60, 80 and 100;

a) Find the coefficients B and D in the Andrade equation. T in the equation is the absolute temperature.

Andrade Equation: = De

B/T

b) Calculate the viscosity of water at 50C. The viscosity of water at 50C is 5.468104 Pas

measured. Accordingly, the % error (difference) for the value calculated with the Andreas equation

calculate.

Hint: To get the coefficients, first write the equation in linear form, then the solution

(you can use MATLAB or MS Excel).

Soru 1) Suyun 5, 20, 40, 60, 80 ve 100C'daki viskozitesinden () yararlanarak; a) Andrade eitliindeki B ve D katsaylarn bulunuz. Denklemdeki T mutlak scaklktir. Andrade Eitlii: y = DEBT b) Suyun 50C'deki viskozitesini hesaplaynz. 50C'ta suyun viskozitesi 5.468x10- Pa-s olarak llmtr. Buna gre Andreas denklemi ile hesaplanan deer iin % hatay (fark) hesaplaynz. pucu: Katsaylara ulaabilmek iin ncelikle denklemi lineer formda yaznz, daha sonra zm yapnz (MATLAB veya MS Excel kullanabilirsiniz)
