Energy, charge and strangeness flow in K+p interactions at 32 and 70 GeV/c, and π+p interactions at 32 GeV/c are studied in terms of the angular variable λ=|x|/pT. The data on dQ/dλ and dE/dλ show only a weak indication of scale breaking between 32 and 70 GeV/c. For inclusive "non-diffractive", inclusive "diffractive" and exclusive "non-diffractive" jets, the fraction of charge in any angular region ΔΩ away from the central region is found to be proportional to the energy fraction in the same interval. The data on dQ/dE versus λ are compatible with some versions of dual-sheet models and agree also with the LUND Monte-Carlo model. The data are also compared with {Mathematical expression} interactions in BEBC. In exclusive channels the average ratio dQ/dS=0.78±0.04 is consistent, in the framework of fragmentation models, with a larger probability for the fragmentation of the {Mathematical expression}-valence quark than the u-valence quark in the K+-meson.
