STEP 1: Convert Input(s) to Base Unit

Power Transmitted: 300 Watt --> 300 Watt No Conversion Required
Length of Underground AC Wire: 24 Meter --> 24 Meter No Conversion Required
Resistance Underground AC: 5 Ohm --> 5 Ohm No Conversion Required
Area of Underground AC Wire: 1.28 Square Meter --> 1.28 Square Meter No Conversion Required
Line Losses: 2.67 Watt --> 2.67 Watt No Conversion Required
Maximum Voltage Underground AC: 230 Volt --> 230 Volt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K = (4*P*L*R*A)/(P_loss*(V_m^2)) --> (4*300*24*5*1.28)/(2.67*(230^2))

Evaluating ... ...

K = 1.30498502580659

STEP 3: Convert Result to Output's Unit

1.30498502580659 --> No Conversion Required

FINAL ANSWER

1.30498502580659 ≈ 1.304985 <-- Constant Underground AC
