GUTTER FLOW PROGRAM
(Example follows instructions)
GUTTER FLOW DOCUMENTATION: GUTTER flow program written in house.
1. Do you want printer On (screen =0 printer =1 both=2)
With the SCREEN option, everything will be displayed on the screen,
therefore, no hard copy will be obtained. With the PRINTER option,
there would be no display of the output on the screen, therefore,
reference must be made to the printout in order to see if the computed
discharge and width of spread is satisfactory, if not then a revised
minimum and maximum depths will be used. With the BOTH option, output
will be displayed both on the PRINTER and on the SCREEN so that the
computed discharge and width of spread could be checked on the SCREEN
without any reference to the printout. If the computed discharge and
width of spread is satisfactory then stop, otherwise use a revised
minimum and maximum depth.
2. Enter GUTTER WIDTH IN FEET
3. Enter GUTR PROF. GRADE (As 0.01)
4. Enter MANNING'S 'N'
5. Enter LANE SLOPE (As 0.01)
6. Enter GUTTER SLOPE (As 0.01)
7. Enter CURB FACE SLOPE (As 0.5)
8. Enter MINIMUM DEPTH (FT.)
9. Enter MAXIMUM DEPTH (FT.)
10. Enter DEPTH INCREMENT
The P.C. will use the above information (2 through 10) to compute a
discharge and corresponding width of spread. If the computed discharge
is close to the design discharge then stop and read the corresponding
width of spread, otherwise use a revised minimum and maximum depth. If
the spread is too wide, then revise the input.
