    The document provides calculations for the design of a perforated distribution plate made of SA 240 Gr. 304L stainless steel. It includes parameters like the plate material, applied loads, design temperature, hole diameter, pitch, thickness. It then outlines a 3 step calculation process: [1] determining the ligament efficiency, [2] calculating the bending stress, and [3] determining the plate deflection. The calculated bending stress of 105.1352 N/mm^2 is found to be less than the allowable stress of 172.5 Mpa.
