Bunker Design—Part 1: Bunker Outlet Design and Initial Measurements of Wall Pressures

Experiments have shown that the Jenike bunker outlet design method is accurate with respect to both the flow pattern (mass flow or funnel flow) and the minimum outlet required. Initial measurements of wall pressures in a 0.6-m-dia mass flow bunker were used to select a suitable measuring technique for use in larger scale equipment, which is also described.
