Duration given Maximum Intensity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Duration of Excess Rainfall in Hours = ((Constant K*(Return Period^Coefficient x)/Maximum Intensity)-Coefficient a^Constant n)^(1/Constant n)
D = ((K*(Tr^x)/imax)-a^n)^(1/n)
This formula uses 7 Variables
Variables Used
Duration of Excess Rainfall in Hours - (Measured in Hour) - Duration of Excess Rainfall in Hours is time during which continuous rain is observed at a given point or within a given area.
Constant K - Constant K is for the catchment to be determined by flood hydrograph characteristics of the catchment.
Return Period - Return Period [Years] is an average time or an estimated average time between events such as earthquakes, floods, landslides, or a river discharge flows to occur.
Coefficient x - Coefficient x for the area represented by the catchment station under consideration.
Maximum Intensity - (Measured in Centimeter per Hour) - Maximum Intensity is the ratio of the total amount of rain (rainfall depth) falling during a given period to the duration of the period.
Coefficient a - Coefficient a for area represented by the station or coefficient for International Passenger Forecast.
Constant n - Constant n is for the catchment to be determined by the effective rainfall of the catchment.
STEP 1: Convert Input(s) to Base Unit
Constant K: 4 --> No Conversion Required
Return Period: 150 --> No Conversion Required
Coefficient x: 1.5 --> No Conversion Required
Maximum Intensity: 266.794 Centimeter per Hour --> 266.794 Centimeter per Hour No Conversion Required
Coefficient a: 0.6 --> No Conversion Required
Constant n: 3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
D = ((K*(Tr^x)/imax)-a^n)^(1/n) --> ((4*(150^1.5)/266.794)-0.6^3)^(1/3)
Evaluating ... ...
D = 3.01208486566622
STEP 3: Convert Result to Output's Unit
10843.5055163984 Second -->3.01208486566622 Hour (Check conversion ​here)
FINAL ANSWER
3.01208486566622 3.012085 Hour <-- Duration of Excess Rainfall in Hours

What is Precipitation?

Precipitation is a form of water from the atmosphere. It is a term in meteorology, and includes rain, snow, sleet, ice pellets dew, frost, and hail. These form by condensation from atmospheric water vapor, and fall under gravity. Fog and mist are not precipitation but suspensions.

How to Calculate Duration given Maximum Intensity?
