Optimum number of rain gauge stations Solution

STEP 0: Pre-Calculation Summary
Formula Used
Optimum Number of Rain Gauge Stations = (Coefficient of Variation of Rainfall/Allowable Degree of Error)^2
N = (Cv/E)^2
This formula uses 3 Variables
Variables Used
Optimum Number of Rain Gauge Stations - Optimum Number of Rain Gauge Stations in a specified catchment.
Coefficient of Variation of Rainfall - Coefficient of Variation of Rainfall at n stations existing in percentage %.
Allowable Degree of Error - Allowable Degree of error in the estimate of mean rainfall in Percentage.
STEP 1: Convert Input(s) to Base Unit
Coefficient of Variation of Rainfall: 10 --> No Conversion Required
Allowable Degree of Error: 6 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
N = (Cv/E)^2 --> (10/6)^2
Evaluating ... ...
N = 2.77777777777778
