1. What is the Boiling Point of Electrolyte Formula?

The formula calculates the boiling point of electrolyte during electrochemical machining of metals. It determines the temperature at which the electrolyte starts to boil based on various process parameters including ambient temperature, electric current, resistance, electrolyte properties, and flow rate.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \theta_B = \theta_o + \frac{I^2 \times R}{\rho_e \times c_e \times q} \]

Where:

\( \theta_B \) — Boiling Point of Electrolyte (K)
\( \theta_o \) — Ambient Air Temperature (K)
\( I \) — Electric Current (A)
\( R \) — Resistance of Gap Between Work And Tool (Ω)
\( \rho_e \) — Density of Electrolyte (kg/m³)
\( c_e \) — Specific Heat Capacity of Electrolyte (J/(kg·K))
\( q \) — Volume Flow Rate (m³/s)

Explanation: The formula accounts for the heat generated by electrical resistance and how it affects the electrolyte's boiling point relative to ambient conditions.

3. Importance of Boiling Point Calculation

Details: Accurate boiling point calculation is crucial for preventing electrolyte vaporization during electrochemical machining, ensuring process stability, and maintaining machining precision.
