Abstract

A centrifugal fan for chemical application in orchard farm, producing air stream with a maximum value of 9.81 m/s was developed and its performance evaluated in the research. The fan performance was evaluated with three parameters, namely: linear velocity (air velocity), fan output power and mechanical efficiency. The fan input power or the shaft power was obtained at different sheave diameters of 110, 130, 150 and 190 mm using established relationships. The fan parameters obtained were subjected to analysis of variance in order to determine if there were significant differences between these parameters at the selected sheave diameters at 95 % confidence level. Findings of the research revealed that the fan input power ranged from 1.2039 to 3.16 kW; the analytical fan output power ranges from 0.0043 to 0.0161 kW; the air velocity ranged from 7.73 to 9.81 m/s; while the airflow rates ranged from 0.0043 to 0.0161 m3/s. The developed centrifugal fan has a maximum of 68.42 % mechanical efficiency, and capable of delivering air stream at a velocity of 9.81 m/s. The calculated parameters were significant at 95 % confidence level at different sheave diameters. The centrifugal fan was found suitable for chemical application in orchard protection operations.
