Monsoon Duration Factor given Run-off in Inches by Lacey's Formula Solution

STEP 0: Pre-Calculation Summary

Formula Used

Monsoon Duration Factor = (Catchment Factor*(Runoff Depth in Inches*Rainfall Depth-Rainfall Depth^2))/(-120*Runoff Depth in Inches)
F_m = (S*(R*P_RD-P_RD^2))/(-120*R)
This formula uses 4 Variables

Variables Used

Monsoon Duration Factor - Monsoon Duration Factor depends on the monsoon rains.
Catchment Factor - Catchment Factor are topography, shape, size, soil type, and land use (paved or roofed areas).
Runoff Depth in Inches - (Measured in Meter) - Runoff Depth in Inches is the measuring point in the receiving water results in the arithmetical mean of the values of the total runoff depth.
Rainfall Depth - (Measured in Meter) - Rainfall Depth is the total amount of rain falling over a catchment area in terms of depth.

STEP 1: Convert Input(s) to Base Unit

Catchment Factor: 2 --> No Conversion Required
Runoff Depth in Inches: 4 Inch --> 0.101600000000406 Meter (Check conversion here)
Rainfall Depth: 5 Inch --> 0.127000000000508 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_m = (S*(R*P_RD-P_RD^2))/(-120*R) --> (2*(0.101600000000406*0.127000000000508-0.127000000000508^2))/(-120*0.101600000000406)

Evaluating ... ...

F_m = 0.000529166666668794

STEP 3: Convert Result to Output's Unit

0.000529166666668794 --> No Conversion Required

FINAL ANSWER

0.000529166666668794 ≈ 0.000529 <-- Monsoon Duration Factor
