Find the total amount of power in watts for a 5 hp, 7 hp and 10 hp group of motors. (One horsepower equals 746 watts)

• A. 15,000 watts
• B. 16,000 watts
• C. 16,412 watts
• D. 18,000 watts

Answer: (C)

Converting total horsepower to watts and summing multiple motors. Add the motor ratings: 5 + 7 + 10 = 22 horsepower. Each horsepower equals 746 watts, so total watts = 22 × 746. Compute: 746 × 22 = 14,920 + 1,492 = 16,412 watts. So the total power is 16,412 watts. The other options don’t fit because they don’t equal the exact conversion of 22 horsepower (e.g., 15,000 W is about 20.1 hp, 16,000 W about 21.5 hp, and 18,000 W about 24.1 hp).
