கருத்து:

மீட்டர் மாறிலி = (சுழற்சியின் எண்ணிக்கை) / (மொத்த ஆற்றல்)

கணக்கீடு:

கொடுக்கப்பட்டால், 10 நிமிடங்களில் சுழற்சிகளின் எண்ணிக்கை = 100

1 மணிநேரத்தில் சுழற்சிகளின் எண்ணிக்கை = 10 × 60

மீட்டர் மாறிலி = 750 rev/kWh

\(750 = \frac{{10 \times 6}}{E}\)

\(\Rightarrow E = \frac{{100 \times 6}}{{750}} = 0.8\;kWh\)
