Time given Rainfall Intensity for Storms having Frequency of 15 Years Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time in Minutes = (K Constant when Storm having Frequency of 15 Year/Rainfall Intensity for Storms Freq of 15 Years)^(1/0.65)-20
T_m = (K_s15/i_st)^(1/0.65)-20
This formula uses 3 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 when Storm having Frequency of 15 Year - (Measured in Meter per Second) - K Constant when Storm having Frequency of 15 Year is empirical constants with specific units as mm/hr.
Rainfall Intensity for Storms Freq of 15 Years - (Measured in Meter per Second) - Rainfall Intensity for Storms Freq of 15 Years is the ratio of the total amount of rain falling during a given period to the duration of the period, considering storm freq of 15 years.

STEP 1: Convert Input(s) to Base Unit

K Constant when Storm having Frequency of 15 Year: 1600 Millimeter per Hour --> 0.000444444444444444 Meter per Second (Check conversion here)
Rainfall Intensity for Storms Freq of 15 Years: 15.77 Millimeter per Hour --> 4.38055555555556E-06 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_m = (K_s15/i_st)^(1/0.65)-20 --> (0.000444444444444444/4.38055555555556E-06)^(1/0.65)-20

Evaluating ... ...

T_m = 1200.66746194966

STEP 3: Convert Result to Output's Unit

1200.66746194966 Second -->20.0111243658276 Minute (Check conversion here)

FINAL ANSWER

20.0111243658276 ≈ 20.01112 Minute <-- Time in Minutes

(Calculation completed in 00.020 seconds)

Intensity of Rain when Time Varying between 5 to 20 Minutes

LaTeX Go Intensity of Rain (Time between 5 to 20 Min) = (K Constant when Time Varying between 5 to 20 Min/(Time in Minutes+Constant b when Time Varying between 5 to 20 Min)^0.5)

Time given Intensity of Rain

LaTeX Go 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

Intensity of Rain for Intensity Duration Curve

LaTeX Go Intensity of Rain for Intensity Duration Curve = K Constant/(Time in Minutes+Empirical Constant b)^0.8

Time in Minutes given Intensity of Rain

LaTeX Go Time in Minutes = (K Constant when Time Varying between 5 to 20 Min/Intensity of Rain (Time between 5 to 20 Min))^(1/0.5)-10

Time given Rainfall Intensity for Storms having Frequency of 15 Years Formula

LaTeX Go

Time in Minutes = (K Constant when Storm having Frequency of 15 Year/Rainfall Intensity for Storms Freq of 15 Years)^(1/0.65)-20
T_m = (K_s15/i_st)^(1/0.65)-20

What is Storm Duration?

Design storm duration is an important parameter. that defines the rainfall depth or intensity for a. given frequency, and therefore affects the. resulting runoff peak and volume.
