Engineering Data 821, 831, 92 Series, 98VOH, H and V Series Drop Chart, Use with size selection charts
The drop of the air stream is determined by using the throw and velocity of the register selected. On the drop chart, lay a straight edge connecting these values. The total drop of the air stream will be the sum of the drop due to temperature (Dt) and the drop due to spread (Ds). Example: The drop for a 92 Series register “C” deflection 16x5 size has an 800 fpm velocity and a 16 foot throw. Connect these two points on the chart and read the drops as follows:
Dt = 2.7’
Engineering Data
Instructions for use of Drop Chart
Ds = 2’
D total = 2.7 + 2 = 4.7’ Dt = Drop along line of throw due to temperature difference. Ds = Drop resulting from vertical spread.

Engineering Data 117
The drop of the air stream is determined by using the throw and velocity of the register selected. On the drop chart, lay a straight edge connecting these values. The total drop of the air stream will be the sum of the drop due to temperature (Dt) and the drop due to spread (Ds). Example: The drop for a 92 Series register “C” deflection 16x5 size has an 800 fpm velocity and a 16 foot throw. Connect these two points on the chart and read the drops as follows:
Dt = 2.7’
Engineering Data
Instructions for use of Drop Chart
Ds = 2’
D total = 2.7 + 2 = 4.7’ Dt = Drop along line of throw due to temperature difference. Ds = Drop resulting from vertical spread.
