Answer:

The inductive reactance is 0.8281 Ω/mile

Explanation:

Given;

frequency, f = 60 Hz

space between the center, GMD = 20 ft

The inductive reactance per mile is calculated as;

X_L =X_a + X_d\\\\X_L = 2.022*10^{-3} *f *ln\frac{1}{GMR} + 2.022*10^{-3} *f *ln\ GMD

Where;

GMR is geometric mean radius (obtained from manufacturer's table)

GMD is geometric mean distance

For Partridge conductor, GMR = 0.0217 ft;

Xa = 2.022 x 10⁻³ x 60 x ln (1 / 0.0217)

Xa = 0.4647 Ω/mile

X_d = 2.022 x 10⁻³ x f x ln GMD

X_d = 2.022 x 10⁻³ x 60 x ln(20)

X_d = 0.3634 Ω/mile

Inductive reactance;

X_L = X_a + X_d\\\\X_L = 0.4647 \ ohms/mile \ +  0.3634 \ ohms/mile\\\\X_L = 0.8281 \ ohms/mile

Therefore, the inductive reactance is 0.8281 Ω/mile

Given below are the measured streamflows in cfs from a storm of 6-hour duration on a stream having a drainage area of 185 mi^2.
sertanlavr [38]

Answer:

33.56 ft^3/sec.in

Explanation:

Duration = 6 hours

drainage area = 185 mi^2

constant baseflow = 550 cfs

<u>Derive the unit hydrograph using the inverse procedure </u>

first step : calculate for the volume of direct runoff hydrograph using the details in table 2 attached below

Vdrh = sum of drh *  duration

        = 29700 * 6 hours ( 216000 secs )

        = 641,520,000 ft^3.

next step : Calculate the volume of runoff in equivalent depth

Vdrh / Area = 641,520,000  / 185 mi^2

                    = 1.49 in

Finally derive the unit hydrograph

Unit of hydrograph = drh /  volume of runoff in equivalent depth

                                = 50 ft^3 / 1.49 in  =  33.56 ft^3/sec.in
