Intensity of Rain for Intensity Duration Curve

Go Intensity of Rainfall = Constant a/(Time in minutes+Constant B)

Time in Minutes given Intensity of Rain

Go Time in minutes = (Constant a/Intensity of Rainfall)-Constant B

Rainfall Intensity for Rain having Frequency of 10 Years

Go Intensity of Rainfall = (38/sqrt(Time in minutes))

Time given Rainfall Intensity for Rain having Frequency of 1 Year

Go Time in minutes = (15/Intensity of Rainfall)^(1/0.620)

Rainfall Intensity for Rain having Frequency of 1 Years

Go Intensity of Rainfall = (15/(Time in minutes)^(0.620))

Intensity of Rain given Time Varying between 20 to 100 Minutes

Go Intensity of Rainfall = (100/(Time in minutes+20))

Rainfall Intensity for Localities where Rainfall is Frequent

Go Intensity of Rainfall = (343/(Time in minutes+18))

Rainfall Intensity for Storms having Frequency of 10 Years

Go Intensity of Rainfall = (267/(Time in minutes+20))

Rainfall Intensity for Storms having Frequency of 15 Years

Go Intensity of Rainfall = (305/(Time in minutes+20))

Intensity of Rain when Time Varying between 5 to 20 Minutes

Go Intensity of Rainfall = (75/(Time in minutes+10))

Time given Rainfall Intensity for Localities where Rainfall is Frequent

Go Time in minutes = (343/Intensity of Rainfall)-18

Time given Rainfall Intensity for Storms having Frequency of 10 Years

Go Time in minutes = (267/Intensity of Rainfall)-20

Time given Rainfall Intensity for Storms having Frequency of 15 Years

Go Time in minutes = (305/Intensity of Rainfall)-20

Time Varying between 20 to 100 Minutes given Intensity of Rain

Go Time in minutes = (100/Intensity of Rainfall)-20

Time given Intensity of Rain

Go Time in minutes = (75/Intensity of Rainfall)-10

Time given Rainfall Intensity for Rain having Frequency of 10 Years

Go Time = (38/Intensity of Rainfall)^2
