Calculating Net Volume #19

Open upsonp opened 10 months ago

upsonp commented 10 months ago

Volume use to be calculated using 'Wire out' in elog, But it should use Flowmeter_End and Flowmeter_Start

Equation as provided by Marc Ringuette: Vol = ((Flowmeter_End - Flowmeter_Start)* 0.3) * (pi * (0.75/2)^2)) 202 mesh Vol = ((Flowmeter_End - Flowmeter_Start)* 0.3) * (pi * (0.5/2)^2)) 76 mesh pi*R^2 where R is the radius of the ring net

I discussed with Marc, it would be handy for e-log to include a "Opening Size" field in elog where the net operator could add the pi*R^2 calculation part of the equation, if the net is square or rectangular then that's the only part of the equation to change.
