Download Solution PDFConcept:
Meter constant = (Number of revolution) / (Total energy)
Calculation:
Given that, number of revolutions = 100 in 10 mins
Number of revolutions in 1 hour = 100 × 6
Meter constant = 750 rev/kWh
\(750 = \frac{{100 \times 6}}{E}\)
\(\Rightarrow E = \frac{{100 \times 6}}{{750}} = 0.8\;kWh\)
