1. What Is The Power Consumption Calculation?

This calculator determines the power consumption in kilowatt-hours (kWh) for a 1 horsepower motor operating for a specified number of hours. It converts mechanical power to electrical energy consumption.

2. How Does The Calculator Work?

The calculator uses the power consumption formula:

Where:

• 1 — Motor horsepower rating
• 0.746 — Conversion factor from horsepower to kilowatts
• Hours — Operating time in hours

Explanation: The formula converts horsepower to kilowatts (1 hp = 0.746 kW) and multiplies by operating hours to get energy consumption in kilowatt-hours.

3. Importance Of Power Consumption Calculation

Details: Calculating power consumption helps in estimating electricity costs, sizing electrical systems, and evaluating energy efficiency of motor-driven equipment.

4. Using The Calculator

Tips: Enter the number of operating hours. The value must be a positive number. The calculator will compute the total energy consumption in kilowatt-hours.

5. Frequently Asked Questions (FAQ)

Q1: Why use 0.746 as the conversion factor?
A: 0.746 is the standard conversion factor from mechanical horsepower to kilowatts (1 hp = 745.7 W ≈ 0.746 kW).

Q2: Does this account for motor efficiency?
A: No, this calculation assumes 100% efficiency. Actual consumption may be higher due to motor inefficiencies and power factor.

Q3: Can I use this for motors with different horsepower ratings?
A: This calculator is specifically for 1 hp motors. For other ratings, multiply the result by the motor's horsepower.

Q4: How accurate is this calculation for cost estimation?
A: It provides a theoretical baseline. Actual costs may vary based on electricity rates, motor efficiency, and operating conditions.

Q5: What's the difference between power and energy?
A: Power (kW) is the rate of energy use, while energy (kWh) is power multiplied by time, representing total consumption.
