A) 30
B) 42
C) 51
D) 67
Correct Answer: D
Solution :
Permeability number, \[P=\frac{Vh}{pAt}\] \[V=2000\,\,c.c.,\] \[t=1.5\,\,\min ,\] \[h=5.08\,\,cm,\] \[d=5.08\,\,cm,\] \[p=5\,\,\text{g/c}{{\text{m}}^{\text{2}}}\] \[P=\frac{2000\times 5.08}{5\times \frac{\pi }{4}\,{{(5.08)}^{2}}\times 1.5}=66.83=67\]You need to login to perform this action.
