Might want to verify the units on viscosity. Using units of N-s/m^2, my tables show 1080*10E-6 at 290K and 959*10E-6 at 295K. As Alchemy noted, my first value should have read 8.9*10E-4 at 25°C. If you're using the same units, it sounds like you are off by a factor of 10. If you're wondering about the "10E-6" vs "10E-4" or the "K" vs "°C", it's the difference between a table in one book (my heat transfer text) and a graph in another (fluids text).
