## Number of rails per km at given weight of rails per km Solution

STEP 0: Pre-Calculation Summary
Formula Used
Number of rails per km = (1000*Weight of Rails per km)/(Length of single rail*Weight of rail per meter)
N = (1000*W)/(L*w)
This formula uses 4 Variables
Variables Used
Number of rails per km - Number of rails per km is the total number of rails in one kilometer or 1000m.
Weight of Rails per km - (Measured in Tonne) - Weight of Rails per km is the total weights of rail in one km distance.
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.
Weight of rail per meter - (Measured in Kilogram per Meter) - Weight of rail per meter means total weight of rail in one meter. 52kg/m (really 51.89kg/m, 105lb/yd) rail is also used extensively.
STEP 1: Convert Input(s) to Base Unit
Weight of Rails per km: 104.104 Tonne --> 104.104 Tonne No Conversion Required
Length of single rail: 13 Meter --> 13 Meter No Conversion Required
Weight of rail per meter: 52 Kilogram per Meter --> 52 Kilogram per Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
N = (1000*W)/(L*w) --> (1000*104.104)/(13*52)
Evaluating ... ...
N = 154
STEP 3: Convert Result to Output's Unit
154 --> No Conversion Required
154 <-- Number of rails per km
