CALCULO DE LA VISCOCIDAD
DONDE:
μ=
1) 10 /0.982 = 10.1823
2) 10.9/1.06= 10.283
3) 11.9/1.16=10.2586
4) 13/1.28= 10.1563
5) 14.1/1.41= 10
6) 15.4/1.54= 10
7) 16.8/1.66= 10.1205
8) 18.3/1.82= 10.0549
9) 20/2.02=9.90099
10) 21.8/2.2=9.909091
11) 23.8/2.42=9.83471
12) 25.9/2.66=9.73684
13) 28.3/2.94=9.62585
14) 30.8/3.26=9.44784
15) 33.6/3.61=9.307489
16) 36.7/4.03=9.1067
17) 40/4.5=8.88889
18) 43.6/5.08=8.56582
19) 47.6/5.8=8.2069
20) 51.9/6.7=7.74627
21) 56.6/8.16=6.93677
22) 61.7/15.3=4.03268
23) 67.3/40=1.6825
24) 73.4/164=0.447561
