Corporate name TU Delft Date 1963-01-01 Abstract Measurements of the turbulent stresses in fully-developed pipe flow have been made as an overall test of the DISA constant-temperature hot-wire anemometer. The measurements were made with single slanting wires and a normal wire. The shearing stress was measured at two Reynolds numbers and compared with values computed from the pressure drop down the pipe: an accuracy of 10% or better was achieved. The computed longitudinal and transverse normal stresses were in good agreement with the measurements of Laufer. It was confirmed that the heat loss from the wire varied linearly with U^0.45 (Collis' law) rather than U^0.50 (King's law).
