The present is the third report on a series of experiments involving forced convection heat transfer in He II. A square function heat pulse is applied to the middle of a copper flow tube, 3 mm in diameter and 2 m long, containing He II. The width and amplitude of the pulse are varied in the different experimental runs. The bath temperature is set at three values of 1.65 K, 1.80 K and 1.95 K. The bath pressure is kept under the saturation vapor pressure. The He II flow velocity is varied between zero and 80 cm/s. The fluid temperature is monitored at eight locations along the flow tube. Experimental temperature profiles are then compared with a numerical solution to the He II energy equation.
