<abstract displayLabel="Summary">The computer programm allows sizing and balancing of local exhaust ventilation branches and mains using the Velocity Pressure method as described in the ACGIH Industrial Ventilation Manual. The program is written in BASIC and is designed for use in any hand-held BASIC-programmable computer such as the Radio Shack TRS-80 Pocket Computer. The user enters branch design data and the program computes duct diameter, with an override option, actual velocity, duct velocity pressure, slot velocity pressure, hood static pressure and static pressure of each branch. It will compare branch static pressures and either identify a branch to be redesigned, or will correct the flow in the branch with lower static pressure, and will call for design data for the main. It concludes with a display of the total losses at the end of the main. A complete listing of the program and a worked-out example are given</abstract>
