Equation for Base Flow into Stream from Area Solution

Follow our step by step solution on how to calculate Equation for Base Flow into Stream from Area?

FIRST Step Consider the formula

B = R G - D G + I s + I - (h \cdot S Y \cdot A)

Next Step Substitute values of Variables

∴

B = 45m³/s - 10m³/s + 18m³/s + 12m³/s - (5m \cdot 0.59 \cdot 20m²)

Next Step Prepare to Evaluate

∴

B = 45 - 10 + 18 + 12 - (5 \cdot 0.59 \cdot 20)

Next Step Evaluate

∴

B = 6.00000000000001m³/s

LAST Step Rounding Answer

∴

B = 6m³/s
