How to Calculate Wind Resistance?
Wind Resistance calculator uses Wind resistance = 0.000017*Exposed area*Velocity of wind^2 to calculate the Wind resistance, The Wind Resistance is caused by the prevailing wind.It also depends upon the angle at which the wind impinges the train.Maximum side wind resistance generally occurs when wind is acting at an angle of 60° to the direction of train movement. Wind resistance is denoted by R_{w} symbol.
How to calculate Wind Resistance using this online calculator? To use this online calculator for Wind Resistance, enter Exposed area (a) & Velocity of wind (V) and hit the calculate button. Here is how the Wind Resistance calculation can be explained with given input values -> 0.839506 = 0.000017*400*11.1111111111111^2.
