Part 3. The wall friction velocity is derived from the experimental velocity at R = 0.4771 diameters. This is done by fitting to a log law if y-plus is greater than 11.22, and to u-plus = y-plus otherwise. The data beyond the experimental domain (3 diameters) is a linear extrapolation with a cut-off at the fully developed pipe flow value (0.00972). The data has been specified at many points so that linear interpolation will give accurate values at any axial position. The (FORTRAN) format used to read the data should be: 3E13.3 Axial Axial Friction position velocity velocity 5.000E-02 3.077E-02 2.129E-03 1.000E-01 2.740E-02 1.928E-03 1.500E-01 2.251E-02 1.630E-03 2.000E-01 1.610E-02 1.226E-03 2.500E-01 8.172E-03 6.939E-04 3.000E-01 -1.283E-03 -2.507E-04 3.500E-01 -1.226E-02 -9.741E-04 4.000E-01 -2.476E-02 -1.768E-03 4.500E-01 -3.878E-02 -2.598E-03 5.000E-01 -5.433E-02 -3.477E-03 5.500E-01 -6.975E-02 -4.321E-03 6.000E-01 -8.341E-02 -5.051E-03 6.500E-01 -9.530E-02 -5.676E-03 7.000E-01 -1.054E-01 -6.201E-03 7.500E-01 -1.138E-01 -6.631E-03 8.000E-01 -1.204E-01 -6.967E-03 8.500E-01 -1.252E-01 -7.213E-03 9.000E-01 -1.283E-01 -7.368E-03 9.500E-01 -1.300E-01 -7.454E-03 1.000E+00 -1.307E-01 -7.491E-03 1.050E+00 -1.305E-01 -7.478E-03 1.100E+00 -1.292E-01 -7.415E-03 1.150E+00 -1.270E-01 -7.303E-03 1.200E+00 -1.238E-01 -7.141E-03 1.250E+00 -1.196E-01 -6.928E-03 1.300E+00 -1.145E-01 -6.665E-03 1.350E+00 -1.087E-01 -6.371E-03 1.400E+00 -1.028E-01 -6.065E-03 1.450E+00 -9.667E-02 -5.747E-03 1.500E+00 -9.036E-02 -5.417E-03 1.550E+00 -8.386E-02 -5.075E-03 1.600E+00 -7.717E-02 -4.720E-03 1.650E+00 -7.030E-02 -4.351E-03 1.700E+00 -6.324E-02 -3.968E-03 1.750E+00 -5.612E-02 -3.577E-03 1.800E+00 -4.909E-02 -3.185E-03 1.850E+00 -4.214E-02 -2.791E-03 1.900E+00 -3.527E-02 -2.394E-03 1.950E+00 -2.849E-02 -1.993E-03 2.000E+00 -2.179E-02 -1.585E-03 2.050E+00 -1.518E-02 -1.166E-03 2.100E+00 -8.643E-03 -7.271E-04 2.150E+00 -2.320E-03 -3.372E-04 2.200E+00 3.668E-03 4.240E-04 2.250E+00 9.321E-03 7.743E-04 2.300E+00 1.464E-02 1.131E-03 2.350E+00 1.962E-02 1.450E-03 2.400E+00 2.427E-02 1.738E-03 2.450E+00 2.858E-02 1.998E-03 2.500E+00 3.256E-02 2.235E-03 2.550E+00 3.660E-02 2.472E-03 2.600E+00 4.111E-02 2.732E-03 2.650E+00 4.609E-02 3.016E-03 2.700E+00 5.155E-02 3.323E-03 2.750E+00 5.747E-02 3.651E-03 2.800E+00 6.386E-02 4.002E-03 2.850E+00 7.072E-02 4.374E-03 2.900E+00 7.805E-02 4.766E-03 2.950E+00 8.585E-02 5.180E-03 3.000E+00 9.412E-02 5.614E-03 3.050E+00 1.006E-01 5.952E-03 3.100E+00 1.072E-01 6.290E-03 3.150E+00 1.137E-01 6.628E-03 3.200E+00 1.204E-01 6.966E-03 3.250E+00 1.270E-01 7.303E-03 3.300E+00 1.337E-01 7.641E-03 3.350E+00 1.405E-01 7.979E-03 3.400E+00 1.472E-01 8.317E-03 3.450E+00 1.540E-01 8.655E-03 3.500E+00 1.609E-01 8.993E-03 3.550E+00 1.678E-01 9.331E-03 3.600E+00 1.746E-01 9.669E-03 3.650E+00 1.757E-01 9.720E-03 3.700E+00 1.757E-01 9.720E-03 3.750E+00 1.757E-01 9.720E-03 3.800E+00 1.757E-01 9.720E-03 3.850E+00 1.757E-01 9.720E-03 3.900E+00 1.757E-01 9.720E-03 3.950E+00 1.757E-01 9.720E-03 4.000E+00 1.757E-01 9.720E-03 4.050E+00 1.757E-01 9.720E-03 4.100E+00 1.757E-01 9.720E-03 4.150E+00 1.757E-01 9.720E-03 4.200E+00 1.757E-01 9.720E-03 4.250E+00 1.757E-01 9.720E-03 4.300E+00 1.757E-01 9.720E-03 4.350E+00 1.757E-01 9.720E-03 4.400E+00 1.757E-01 9.720E-03 4.450E+00 1.757E-01 9.720E-03 4.500E+00 1.757E-01 9.720E-03 4.550E+00 1.757E-01 9.720E-03 4.600E+00 1.757E-01 9.720E-03 4.650E+00 1.757E-01 9.720E-03 4.700E+00 1.757E-01 9.720E-03 4.750E+00 1.757E-01 9.720E-03 4.800E+00 1.757E-01 9.720E-03 4.850E+00 1.757E-01 9.720E-03 4.900E+00 1.757E-01 9.720E-03 4.950E+00 1.757E-01 9.720E-03 5.000E+00 1.757E-01 9.720E-03 5.050E+00 1.757E-01 9.720E-03 5.100E+00 1.757E-01 9.720E-03 5.150E+00 1.757E-01 9.720E-03 5.200E+00 1.757E-01 9.720E-03 5.250E+00 1.757E-01 9.720E-03 5.300E+00 1.757E-01 9.720E-03 5.350E+00 1.757E-01 9.720E-03 5.400E+00 1.757E-01 9.720E-03 5.450E+00 1.757E-01 9.720E-03 5.500E+00 1.757E-01 9.720E-03 5.550E+00 1.757E-01 9.720E-03 5.600E+00 1.757E-01 9.720E-03 5.650E+00 1.757E-01 9.720E-03 5.700E+00 1.757E-01 9.720E-03 5.750E+00 1.757E-01 9.720E-03 5.800E+00 1.757E-01 9.720E-03 5.850E+00 1.757E-01 9.720E-03 5.900E+00 1.757E-01 9.720E-03 5.950E+00 1.757E-01 9.720E-03 6.000E+00 1.757E-01 9.720E-03 * * * * * * * * * * * * * *
