Obtain the relationship for conductance in viscous flow regime.
Determine the conductance of a 1cm diameter tube, 30 cm long is used at pressure from 10 torr to 1 torr.
what is the effect on conductance if the tube length is doubled?
if the diameter of the tube is doubled to 2cm what will be the new conductance(L=30cm)?
