Number of Sleepers per km Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Sleepers per Km = (Length of Single Rail+Density Factor)*(Number of Rails per Km)/2
N_s = (L+x)*(N)/2
This formula uses 4 Variables

Variables Used

Number of Sleepers per Km - Number of Sleepers per Km is the total number of sleepers required in one km.
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 - 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 Rails per Km - Number of Rails per Km is the total number of rails in one kilometer or 1000m.

STEP 1: Convert Input(s) to Base Unit

Length of Single Rail: 13 Meter --> 13 Meter No Conversion Required
Density Factor: 6 --> No Conversion Required
Number of Rails per Km: 154 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_s = (L+x)*(N)/2 --> (13+6)*(154)/2

Evaluating ... ...

N_s = 1463

STEP 3: Convert Result to Output's Unit

1463 --> No Conversion Required

FINAL ANSWER

1463 <-- Number of Sleepers per Km

(Calculation completed in 00.004 seconds)
