## Density Factor at given number of sleepers per km Solution

STEP 0: Pre-Calculation Summary
Formula Used
Density Factor = (2*Number of sleepers per km/Number of rails per km)-(Length of single rail)
x = (2*Ns/N)-(L)
This formula uses 4 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.
Number of sleepers per km - Number of sleepers per km is the total number of sleepers required in one km.
Number of rails per km - Number of rails per km is the total number of rails in one kilometer or 1000m.
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.

## Density Factor at given number of sleepers per km Formula

Density Factor = (2*Number of sleepers per km/Number of rails per km)-(Length of single rail)
x = (2*Ns/N)-(L)

## What is the function of sleepers?

The primary function of a sleeper is to grip the rail to gauge and to distribute the rail loads to ballast with acceptable induced pressure. The side functions of a sleeper include the avoidance of both longitudinal and lateral track movement. It also helps to enhance correct line and level of the rails.

## How to Calculate Density Factor at given number of sleepers per km?

Density Factor at given number of sleepers per km calculator uses Density Factor = (2*Number of sleepers per km/Number of rails per km)-(Length of single rail) to calculate the Density Factor, The Density Factor at given number of sleepers per km formula is defined as the number of sleepers required under one rail length of railway track.
