Equation 1 · Part 4 · The Fifteen-Point-Six-Terawatt Number Is Real Arithmetic Built on the Wrong Fleet Size

Symbol H_r

F=L×HwHrF = \frac{L \times H_w}{H_r}
HrH_r

What this part means

the duty-cycle-adjusted operating hours.

Its job in the formula

HrH_r occurs below the fraction bar. The quantity above the bar is divided by this expression; zero is excluded as a denominator.

Where the article explains it

for fleet size F across all nine combinations of the labor-force total L , the hours-worked bracket HwH_w , and the duty-cycle-adjusted operating hours HrH_r , produces a range from about 0.76 billion units (90 percent duty cycle, 1,600 hours worked) to about 1.88 billion units (50 percent duty cycle, 2,200 hours worked), with a representative central case — 70 percent duty cycle, 1,750 hours worked — landing at roughly 1.07 billion units.

The passage around this formula

…respectively. Solving the labor-hours ledger, F=L×HwHrF = \frac{L \times H_w}{H_r}. for fleet size F across all nine combinations of the labor-force total L , the hours-worked bracket HwH_w , and the duty-cycle-adjusted operating hours HrH_r , produces a range from about 0.76 billion units (90 percent duty cycle, 1,600 hours worked) to about 1.88 billion units (50 percent duty cycle, 2,200 hours worked), with a representative central case — 70 percent duty cycle, 1,750 hours worked — landing at roughly 1.07 billion units. That is…
