DEVELOPMENT OF A TERMINAL VELOCITY MEASURING DEVICE FOR GRAINS
A terminal velocity measuring device was developed using locally available materials to assist indigenous designers in determining the terminal velocity of local grains. The device consists of a frame, electric motor, elbow, regulator/control switch, fan/impeller, anemometer and observation column. The device was evaluated using three varieties of grains of Paddy Rice, Sorghum and Beans. The result showed terminal velocity values of 6.95 Â± 0.37, 4.71 Â± 0.24 and 10.98 Â± 0.27ms-1 for Paddy Rice, Sorghum and Beans respectively. Efficiency of the machine was found to be 70.06%. This terminal velocity device can be used efficiently by indigenous designers to determine the terminal velocity of grains for their design work.
