Here is how the Daily Surface Outflow from Lake equation looks like.

2 = 50 + 3 + 5 - 4 - 1958 - 70 - 22

2m³/s = 50mm + 3m³/s + 5m³/s - 4m³/s - 1958mm - 70mm - 22mm

2 = 50 + 3 + 5 - 4 - 1958 - 70 - 22

Daily Surface Outflow from Lake Solution

Follow our step by step solution on how to calculate Daily Surface Outflow from Lake?

FIRST Step Consider the formula

V os = P + V is + V ig - V og - E L - ΔS L - T L

Next Step Substitute values of Variables

∴

V os = 50mm + 3m³/s + 5m³/s - 4m³/s - 1958mm - 70mm - 22mm

Next Step Convert Units

∴

V os = 0.05m + 3m³/s + 5m³/s - 4m³/s - 1.958m - 0.07m - 0.022m

Next Step Prepare to Evaluate

∴

V os = 0.05 + 3 + 5 - 4 - 1.958 - 0.07 - 0.022

LAST Step Evaluate

∴

V os = 2m³/s
