1. What is the kg/h to g/kWh Conversion?

The kg/h to g/kWh conversion calculates specific consumption, which measures fuel or resource efficiency in terms of mass consumed per unit of energy produced. It's commonly used in power generation and engine performance analysis.

2. How Does the Calculator Work?

The calculator uses the conversion equation:

Where:

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

Explanation: The equation converts mass flow per hour to mass per kilowatt-hour by accounting for the power output and converting kilograms to grams.

3. Importance of Specific Consumption

Details: Specific consumption is a key metric for comparing the efficiency of different power systems, engines, or processes. Lower values indicate better efficiency (less fuel/resource consumed per unit of energy produced).

4. Using the Calculator

Tips: Enter mass flow rate in kg/h and power output in kW. Both values must be positive numbers. The calculator will output the specific consumption in g/kWh.

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: Diesel engines typically range 200-250 g/kWh, gas turbines 300-400 g/kWh, and steam plants 400-600 g/kWh, but values vary widely by technology.

Q3: Can this be used for any mass flow to energy ratio?
A: Yes, the calculation works for any mass-to-energy conversion, not just fuel consumption (e.g., water consumption in hydro plants).

Q4: Why multiply by 1000?
A: The factor converts kilograms to grams (1 kg = 1000 g) to give results in the standard g/kWh unit.

Q5: How does this relate to efficiency?
A: For fuel consumption, lower g/kWh values indicate higher efficiency. The theoretical minimum depends on the fuel's energy content.
