It is possible to make engineering calculations in Microsoft Excel. Heres how:
Example: Calculating Delta V for a Rocket
- Define the Calculation: To calculate delta V (change in velocity) for a rocket, engineers can use the rocket equation:
ΔV = V_e * ln(m_0 / m_f)
Where:
ΔV = change in velocity (m/s)
V_e = effective exhaust velocity (m/s)
m_0 = initial total mass (kg)
m_f = final total mass (kg)
- Create a Spreadsheet: Create a new spreadsheet in Excel to perform the calculation.
- Input Data: Input the data required for the calculation into the spreadsheet, such as the effective exhaust velocity (V_e), initial total mass (m_0), and final total mass (m_f).
- Create Formulas: In the spreadsheet, create a formula to calculate the change in velocity (ΔV) using the equation given above:
ΔV = V_e * LN(m_0 / m_f)
- Validate the Calculation: Validate the calculation by inputting sample data and checking that the results are accurate.
- Document the Calculation: Document the calculation by adding a description of the calculation and the formulas used to perform it in the spreadsheet.
But instead of using Excel, use a tool that has inbuilt formulae and automatic calculations.
