## Natural Increase when Design Period is Given Solution

STEP 0: Pre-Calculation Summary
Formula Used
natural_increase = Design period*((Average birth rate per year*Present population)-(Average death rate per year*Present population))
N = T*((IB*P)-(ID*P))
This formula uses 4 Variables
Variables Used
Design period - Design period is the time span for which any particular water related structure is constructed. (Measured in Year)
Average birth rate per year - Average birth rate per year the arithmetic average of total birth within a year. (Measured in 1 Per Year)
Present population- Present population is the known population of city in the given year.
Average death rate per year - Average death rate per year is the arithmetic mean of numbers of death within a year. (Measured in 1 Per Day)
STEP 1: Convert Input(s) to Base Unit
Design period: 20 Year --> 631139040 Second (Check conversion here)
Average birth rate per year: 3 1 Per Year --> 9.50662155204343E-08 1 Per Second (Check conversion here)
Present population: 20 --> No Conversion Required
Average death rate per year: 10 1 Per Day --> 0.000115740740740741 1 Per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
N = T*((IB*P)-(ID*P)) --> 631139040*((9.50662155204343E-08*20)-(0.000115740740740741*20))
Evaluating ... ...
N = -1459770
STEP 3: Convert Result to Output's Unit
-1459770 --> No Conversion Required
FINAL ANSWER
-1459770 <-- Natural increase
(Calculation completed in 00.048 seconds)
