Dimensional homogeneity

The term dimensional homogeneity means that in an equation, the dimensions of each term on both sides are equal, which means the dimensions of the left-hand side (LHS) of an equation are similar to the dimensions of the right-hand side (RHS). For a dimensionally homogeneous equation, the powers of fundamental dimensions will be identical on both sides of the equation.

Estimate ∅-index for a watershed having an area 5 acres. The runoff volume caused by the rainfall is 56000 ft^3. Round off your answer to the nearest whole number. Indicate the unit. Plot the hyetograph and superimpose the final ∅-index. (1 acre = 43560 ft^2) * Using the rounded-off ∅-index, estimate the volume of infiltration losses in cubic feet. *
The 60-year record shows that the annual maximum discharges for a river have a mean of 30,000 cfs, a standard deviation of 28,000 cfs, and a skewness coefficient of 3.15.
