how to find evapotranspiration in energyplus

Hi, I'm doing my graduation project. I'd like you to help me. I'm designing a smart farm now, so the evapotranspiration of the plant is important. Referring to the energy plus guide, it seems like I have to use something in ems, but I don't know how to do it. If I click ems tap, I don't think there's a table to enter a value. How do I get the evapotranspiration? I found this basic formula.

@chloe it doesn't look like the formula was added correctly -- can you please edit your post and add the formula?

Assuming you are talking about the IndoorLivingWall object, there is a Indoor Living Wall Evapotranspiration Rate output variable (in kg/(m^2-s)) as documented here.

EMS is only needed if you want to override the value that EnergyPlus is calculating.
