Relaxation measurments in superfluid /sup 3/He-/sup 4/He mixtures when a heat flux across a horizontal layer is switched on or off provide a quantitative test for the solutions of Khalatnikov's hydrodynamic equations. On the basis of these equations we predict that the relaxation times tau in a layer of height d can be expressed by a simple scaled relation that is a function of static and transport properties. Relaxation experiments on five mixtures are in good agreement with these prediction. In an appendix we discuss the viscous penentration depth lambda/sub p/ and show that it is small enough for the Khalatnikov expressions to be valid under our experimental conditions.
