Energy Conversion Formula:
From: | To: |
Definition: This calculator converts the volume of diesel fuel in litres to electrical energy output in kilowatt-hours (kWh).
Purpose: It helps estimate the potential energy content in diesel fuel, useful for energy planning, generator sizing, and fuel efficiency calculations.
The calculator uses the formula:
Where:
Explanation: The formula calculates the mass of diesel from its volume, determines its energy content, and converts it to electrical energy units.
Details: Accurate energy conversion helps in proper generator sizing, fuel budgeting, and understanding energy efficiency in diesel-powered systems.
Tips: Enter the diesel volume in litres, density (default 0.832 kg/L), and calorific value (default 45.5 MJ/kg). All values must be > 0.
Q1: What is the typical density of diesel?
A: Standard diesel density is about 0.832 kg/L at 15°C, but this varies slightly with temperature and diesel type.
Q2: What calorific value should I use?
A: Typical diesel CV is 45.5 MJ/kg, but check your fuel specifications as this can vary by 1-2 MJ/kg.
Q3: Does this account for conversion efficiency?
A: No, this calculates theoretical energy content. Actual output depends on generator or engine efficiency (typically 30-45%).
Q4: How do I estimate generator runtime?
A: Divide the kWh result by your generator's kW rating to estimate hours of operation at full load.
Q5: Can I use this for biodiesel blends?
A: Yes, but adjust density and CV values as biodiesel typically has slightly lower energy content (about 37-40 MJ/kg).
