Time given Intensity of Rain Solution

STEP 0: Pre-Calculation Summary
Formula Used
Time in Minutes = (K Constant/Intensity of Rain for Intensity Duration Curve)^(1/0.8)-Constant b when Time Varying between 5 to 20 Min
Tm = (K/iidf)^(1/0.8)-b5-20
This formula uses 4 Variables
Variables Used
Time in Minutes - (Measured in Second) - Time in Minutes is a unit of time equal to 60 seconds or 1/60th of an hour.
K Constant - (Measured in Meter per Second) - K Constant is empirical constants with specific units as mm/hr.
Intensity of Rain for Intensity Duration Curve - (Measured in Meter per Second) - Intensity of Rain for Intensity Duration Curve is used to describe the relationship between the intensity of rainfall, the duration of the rainfall, and the frequency of the event.
Constant b when Time Varying between 5 to 20 Min - (Measured in Second) - Constant b when Time Varying between 5 to 20 Min is empirical constants with specific units as minute.
STEP 1: Convert Input(s) to Base Unit
K Constant: 100 Millimeter per Hour --> 2.77777777777778E-05 Meter per Second (Check conversion ​here)
Intensity of Rain for Intensity Duration Curve: 0.24 Millimeter per Hour --> 6.66666666666667E-08 Meter per Second (Check conversion ​here)
Constant b when Time Varying between 5 to 20 Min: 10 Minute --> 600 Second (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Tm = (K/iidf)^(1/0.8)-b5-20 --> (2.77777777777778E-05/6.66666666666667E-08)^(1/0.8)-600
Evaluating ... ...
Tm = 1282.50417418718
STEP 3: Convert Result to Output's Unit
1282.50417418718 Second -->21.3750695697863 Minute (Check conversion ​here)
FINAL ANSWER
21.3750695697863 21.37507 Minute <-- Time in Minutes

What is Rainfall Intensity?

Rainfall intensity is defined as the ratio of the total amount of rain (rainfall depth) falling during a given period to the duration of the period It is expressed in depth units per unit time, usually as mm per hour (mm/h).

How to Calculate Time given Intensity of Rain?

Time given Intensity of Rain calculator uses Time in Minutes = (K Constant/Intensity of Rain for Intensity Duration Curve)^(1/0.8)-Constant b when Time Varying between 5 to 20 Min to calculate the Time in Minutes, The Time given Intensity of Rain formula is defined as the calculation of the time in minutes when we have prior information of intensity of rainfall. Time in Minutes is denoted by Tm symbol.

FAQ

What is Time given Intensity of Rain?
The Time given Intensity of Rain formula is defined as the calculation of the time in minutes when we have prior information of intensity of rainfall and is represented as Tm = (K/iidf)^(1/0.8)-b5-20 or Time in Minutes = (K Constant/Intensity of Rain for Intensity Duration Curve)^(1/0.8)-Constant b when Time Varying between 5 to 20 Min. K Constant is empirical constants with specific units as mm/hr, Intensity of Rain for Intensity Duration Curve is used to describe the relationship between the intensity of rainfall, the duration of the rainfall, and the frequency of the event & Constant b when Time Varying between 5 to 20 Min is empirical constants with specific units as minute.
How to calculate Time given Intensity of Rain?
The Time given Intensity of Rain formula is defined as the calculation of the time in minutes when we have prior information of intensity of rainfall is calculated using Time in Minutes = (K Constant/Intensity of Rain for Intensity Duration Curve)^(1/0.8)-Constant b when Time Varying between 5 to 20 Min. To calculate Time given Intensity of Rain, you need K Constant (K), Intensity of Rain for Intensity Duration Curve (iidf) & Constant b when Time Varying between 5 to 20 Min (b5-20). With our tool, you need to enter the respective value for K Constant, Intensity of Rain for Intensity Duration Curve & Constant b when Time Varying between 5 to 20 Min and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Time in Minutes?
In this formula, Time in Minutes uses K Constant, Intensity of Rain for Intensity Duration Curve & Constant b when Time Varying between 5 to 20 Min. We can use 3 other way(s) to calculate the same, which is/are as follows -
