Question #4.1
Given:
ˁ = 1.0 g/cc
ʼ = 1 cp
d = 5 in.
q = 100 B/D
(a) Find N from Fig. 4.2 .
(b) What kind of flow would you expect?
Returning to the problem of correcting flowmeter-measured velocities to super-
ficial velocities we can now quantify the correction factor as a function of the
Reynolds number. Figure 4.3 plots the correction factor directly as a function of N .
