## Density factor using sleeper density Solution

STEP 0: Pre-Calculation Summary
Formula Used
Density Factor = Sleeper density-Length of single rail
x = S.D.-L
This formula uses 3 Variables
Variables Used
Density Factor - Density factor is any number which when added to a length of rail, will give sleeper Density. In India x-4, 5, 6 or 7 is used for main-tracks.
Sleeper density - Sleeper density is defined as the number of sleepers required under one rail length of railway track. It is expressed as (n + x) where n is the length of one rail in meter and x is constant.
Length of single rail - (Measured in Meter) - Length of Single Rail Indian Railways has standardized a rail length of 13 m (previously 12.8 m) for broad gauge and 12 m (previously 11.8 m) for MG and NG tracks.
STEP 1: Convert Input(s) to Base Unit
Sleeper density: 19 --> No Conversion Required
Length of single rail: 13 Meter --> 13 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
x = S.D.-L --> 19-13
Evaluating ... ...
x = 6
STEP 3: Convert Result to Output's Unit
6 --> No Conversion Required
6 <-- Density Factor
