1. What is Specific Consumption?

Specific consumption (g/kWh) measures how many grams of fuel or substance are consumed per kilowatt-hour of energy produced. It's a key metric for evaluating efficiency in power generation and industrial processes.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( kg/h \) — Mass flow rate in kilograms per hour
• \( Power\_kW \) — Power output in kilowatts
• 1000 — Conversion factor (kg to g)

Explanation: The formula converts the mass flow rate from kg/h to g/h (by multiplying by 1000) and then divides by the power output to get consumption per kWh.

3. Importance of Specific Consumption

Details: Specific consumption is crucial for monitoring efficiency, comparing performance between systems, and identifying potential issues in energy production processes.

4. Using the Calculator

Tips: Enter mass flow rate in kg/h and power output in kW. Both values must be positive numbers for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why convert kg/h to g/kWh?
A: g/kWh is a standard unit for specific fuel consumption that allows easy comparison between different systems regardless of their size.

Q2: What are typical values for specific consumption?
A: Values vary widely by application. Diesel generators might range 200-300 g/kWh, while large gas turbines might be 100-200 g/kWh.

Q3: Can this be used for any substance?
A: Yes, the calculation works for any mass flow (fuel, water, chemicals) where you want to measure consumption per energy unit.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise, but accuracy depends on the precision of your input measurements.

Q5: What if my power is in MW instead of kW?
A: Convert MW to kW by multiplying by 1000 before entering the value (1 MW = 1000 kW).
