Total Storm Precipitation when W Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Storm Precipitation = (W-Index*Duration of Rainfall Excess)+Total Storm Runoff+Depression and Interception Losses
P = (W*t_e)+R+I_a
This formula uses 5 Variables

Variables Used

Total Storm Precipitation - (Measured in Centimeter) - Total Storm Precipitation is the annual precipitation of the current year.
W-Index - (Measured in Centimeter) - W-Index is the average infiltration rate during the time when the rainfall intensity exceeds the infiltration rate.
Duration of Rainfall Excess - (Measured in Hour) - Duration of Rainfall Excess is the total time in which the rainfall intensity the greater than the average rate of infiltration (in hours).
Total Storm Runoff - (Measured in Centimeter) - Total Storm Runoff is rain that flows off building rooftops, driveways, lawns, streets, parking lots, construction sites, and industrial storage yards.
Depression and Interception Losses - (Measured in Centimeter) - Depression and Interception Losses is the portion of the precipitation that is returned to the atmosphere through evaporation from plant surfaces .

STEP 1: Convert Input(s) to Base Unit

W-Index: 16 Centimeter --> 16 Centimeter No Conversion Required
Duration of Rainfall Excess: 4 Hour --> 4 Hour No Conversion Required
Total Storm Runoff: 48 Centimeter --> 48 Centimeter No Conversion Required
Depression and Interception Losses: 6 Centimeter --> 6 Centimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = (W*t_e)+R+I_a --> (16*4)+48+6

Evaluating ... ...

P = 118

STEP 3: Convert Result to Output's Unit

1.18 Meter -->118 Centimeter (Check conversion here)

FINAL ANSWER

118 Centimeter <-- Total Storm Precipitation

Duration of Rainfall Excess given W Index

Go Duration of Rainfall Excess = (Total Storm Precipitation-Total Storm Runoff-Depression and Interception Losses)/W-Index

Total Storm Precipitation when W Index

Go Total Storm Precipitation = (W-Index*Duration of Rainfall Excess)+Total Storm Runoff+Depression and Interception Losses

Total Storm Runoff given W Index

Go Total Storm Runoff = Total Storm Precipitation-Depression and Interception Losses-(W-Index*Duration of Rainfall Excess)

Initial Losses given W-Index

Go Depression and Interception Losses = Total Storm Precipitation-Total Storm Runoff-(W-Index*Duration of Rainfall Excess)

W-Index

Go W-Index = (Total Storm Precipitation-Total Storm Runoff-Depression and Interception Losses)/Duration of Rainfall Excess

Total Storm Precipitation when W Index Formula

Total Storm Precipitation = (W-Index*Duration of Rainfall Excess)+Total Storm Runoff+Depression and Interception Losses
P = (W*t_e)+R+I_a

What is W-Index?

W-Index is the average infiltration rate during the time when the rainfall intensity exceeds the infiltration rate. Thus, W may be mathematically calculated by dividing the total infiltration. (expressed as a depth of water) divided by the time during which the rainfall occurs.

What is Total Storm Precipitation?

In meteorology, total storm precipitation is any product of the condensation of atmospheric water vapour that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail.

How to Calculate Total Storm Precipitation when W Index?

Total Storm Precipitation when W Index calculator uses Total Storm Precipitation = (W-Index*Duration of Rainfall Excess)+Total Storm Runoff+Depression and Interception Losses to calculate the Total Storm Precipitation, The Total Storm Precipitation when W Index formula is defined as any product of the condensation of atmospheric water vapour that falls under gravitational pull from clouds. Total Storm Precipitation is denoted by P symbol.

How to calculate Total Storm Precipitation when W Index using this online calculator? To use this online calculator for Total Storm Precipitation when W Index, enter W-Index (W), Duration of Rainfall Excess (t_e), Total Storm Runoff (R) & Depression and Interception Losses (I_a) and hit the calculate button.
