Re: [TRNSYS-users] TRNSYS input file (***.air)

Remon,
 The second number is the flow coefficient and the third number is the flow exponent in the equation that relates the flow through the opening to the pressure difference across the opening. I am not sure what the first value is or how it is computed.
Kind regards,
 David

Hi everyone,

In the TRNSYS input file of Contam (***.air) we will find some 'flow elements' datas, consisting of 3 values numbers on each line, like the example below (for 5 flow elements):

....
-999 wind pressure profiles:
1 2 5
 0 -1 -0.00625 6.94444e-005 0
 90 -1 0.00625 6.94444e-005 -5.14403e-007
 180 -0.25 0.00625 -6.94444e-005 0
 270 -0.25 -0.00625 -6.94444e-005 5.14403e-007
 360 -1 0 0 0
...etc
-999 flow elements:
1 0.0321663 0.94 0.5
2 0.090255 1.87 0.5
3 0.25528 3.74 0.5
4 0.723488 7.49 0.5
5 0.0176262 1.08102 0.5
.... etc


In the example above, what values are represented by the 3 bold numbers (0.0176262,  1.08102,  0.5) ??

How to calculate the value of 0.0176262 ?

Thank for the help

remon
