Based on energetic considerations, we deduce a simple link between the detonation velocity D of an explosive and its Gurney energy E G , namely $\rm{ \sqrt {2E_G } = D/3.08}$ . The calculations rely on classical results of detonation theory, linked to the assumption of adiabatic expansion of the gaseous detonation products.
