Equation for Gross Recharge due to Rainfall and other Sources Solution

Follow our step by step solution on how to calculate Equation for Gross Recharge due to Rainfall and other Sources?

FIRST Step Consider the formula
RG=(h⋅SY⋅A)+DG+B-Is-I
Next Step Substitute values of Variables
∴ RG=(5m⋅0.59⋅20m²)+10m³/s+6m³/s-18m³/s-12m³/s
Next Step Prepare to Evaluate
∴ RG=(5⋅0.59⋅20)+10+6-18-12
LAST Step Evaluate
∴RG=45m³/s
