. The data, thus expressed, are shown in Fig. 6. As would be expected
the transfer coefficient is larger for bolus flow than for idealized bolus flow, especially
for the larger values of Kl/4uoa2. The per cent difference between the
curve and the experimental points is a measure of the greater transporting efficiency
of bolus flow as compared to Poiseuille flow. This measure of the transport efficiency
in terms of the dimensionless parameters Nu and p.
is dependent only on the value of the dimensionless parameter 8. If we calculate 8
for the capillary, the transport efficiency will be given by this graph.
The form of behaviour in the model suggests application particularly to the pulmonary
capillary. (Conditions of diffusion are more complicated in peripheral
