New formulas are suggested for the swarm speed of cap-shaped gas bubbles collectively rising within a gas-solid fluidized bed. Their derivation stems from comparing the added mass of a single bubble and a swarm of bubbles. For different flow conditions, there are different trends in the dependence of the added mass on the bubble concentration (voidage). This variance translates into different predictions of the suggested swarm speed formulas. This difference is explained in terms of the geometrical configuration of bubbles inside the bed.
