(Slope and roughness are entered the same as for ROUND PIPE
previously.) Then:
MANNING RECTANGULAR
WIDTH=X.XXX FEET (or meters)
If you select TRAPEZOID for the Manning flow conversion, the
following displays will appear:
MANNING TRAPEZOID
SLOPE=X.XXXXX ROUGH=X.XXX
(Slope and roughness are entered as for ROUND PIPE previ-
ously.) Then:
MANNING TRAPEZOID
TOP WIDTH=X.XXX FEET (or meters)
Then:
MANNING TRAPEZOID
BOTTOM WIDTH=X.XXX FEET (or meters)
Returning to Step 2, FLOW CONVERSION TYPE, if you select
DATA POINTS, the following will appear:
SELECT DATA SET
• ONE • • TWO • • THREE • • FOUR • • (NONE) •
Then:
LEVEL UNITS FOR DATA POINT ENTRY
• FT • • IN • • M • • MM •
This allows you to enter data points that are in different units
than what you are using. Then:
FLOW RATE UNITS
• GPM • • GPS • • MGD • • CFS • • CFM • • M3S • • M3H • • M3D •
If you press the right arrow key several times, the following
units will appear on the display:
FLOW RATE UNITS
• LPS • • CFD • • GPH • • AFD • • CFH • • CFM • • M3M •
GPM = gallons per minute; GPS = gallons per second, MGD =
million gallons per day, CFS = cubic feet per second; CFM = cubic
feet per minute, M3S = cubic meters per second; M3M = cubic
meters per minute; M3H = cubic meters per hour; M3D = cubic
meters per day; LPS = liters per second; CFD = cubic feet per
day; GPH = gallons per hour; AFD = acre-feet per day; CFH =
cubic feet per hour.
