Actual Evapotranspiration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Actual Evapotranspiration = Precipitation-Change in Moisture Storage-Surface Runoff-Subsurface Outflow
E_act = P-ΔS-S_r-G_o
This formula uses 5 Variables

Variables Used

Actual Evapotranspiration - (Measured in Cubic Meter per Second) - Actual Evapotranspiration is the quantity of water that is actually removed from a surface due to the processes of evaporation and transpiration.
Precipitation - (Measured in Meter) - Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations.
Change in Moisture Storage - (Measured in Meter) - Change in Moisture Storage is the total amount of water that is stored within the specified reservoir or catchment area.
Surface Runoff - (Measured in Cubic Meter per Second) - Surface Runoff water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle.
Subsurface Outflow - (Measured in Cubic Meter per Second) - Subsurface Outflow is the flow of water beneath earth's surface as part of the water cycle.

STEP 1: Convert Input(s) to Base Unit

Precipitation: 0.3 Meter --> 0.3 Meter No Conversion Required
Change in Moisture Storage: 0.02 Meter --> 0.02 Meter No Conversion Required
Surface Runoff: 0.05 Cubic Meter per Second --> 0.05 Cubic Meter per Second No Conversion Required
Subsurface Outflow: 0.07 Cubic Meter per Second --> 0.07 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E_act = P-ΔS-S_r-G_o --> 0.3-0.02-0.05-0.07

Evaluating ... ...

E_act = 0.16

STEP 3: Convert Result to Output's Unit

0.16 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.16 Cubic Meter per Second <-- Actual Evapotranspiration
