This document provides a 10 step design for aeration of bulk corn storage in a 6m x 5m x 4m bin. It involves: 1) Selecting a design moisture of 13% and calculating generated heat of 149.66 kJ/ton/day. 2) Determining the design day based on local weather data and calculating equilibrium relative humidity. 3) Determining hours of operation per day as 6.5 hours when RH is below equilibrium. 4) Calculating air needed as 49.88 kg/ton/day for a 3°C temperature rise. 5) Selecting a 20" diameter, 3HP fan that can deliver 45.5 m3/min of air
