It is one of two principal mechanisms of exchange by which oxygen and carbon dioxide move between the environment and the tissues, the other being diffusion. Local flows (e.g., through skeletal muscles during exercise) can be increased selectively, increasing the exchange of gases between tissue cells and the capillaries. mass flow [′mas ′flō] (engineering) A pattern of powder flow occurring in hoppers that is characterized by the powder flowing at every point, including points adjacent to the hopper wall.

Mass flow sensors are mounted in the upper clean grain elevator housing. Instead, they use one or more vertical rotating discs that create parallel feeding ducts said to provide positive displacement and linear mass flow, as well as quick cleanout. The Bulkflow heat exchanger uses mass flow and a bank of evenly spaced vertical hollow plates connected to a cooling water system to effectively cool bulk powder. |
