Gap spacing Solution

Follow our step by step solution on how to calculate Gap spacing?

FIRST Step Consider the formula

h = {(\frac{Q \cdot 6 \cdot μ v \cdot \ln (\frac{R 0}{R 1})}{π \cdot (P 1 - P atm)})}^{\frac{1}{3}}

Next Step Substitute values of Variables

∴

h = {(\frac{0.18m³/s \cdot 6 \cdot 10.2P \cdot \ln (\frac{5cm}{4cm})}{π \cdot (11N/cm² - 10N/cm²)})}^{\frac{1}{3}}

Next Step Substitute values of Constants

∴

h = {(\frac{0.18m³/s \cdot 6 \cdot 10.2P \cdot \ln (\frac{5cm}{4cm})}{3.1416 \cdot (11N/cm² - 10N/cm²)})}^{\frac{1}{3}}

Next Step Convert Units

∴

h = {(\frac{0.18m³/s \cdot 6 \cdot 1.02Pa*s \cdot \ln (\frac{0.05m}{0.04m})}{3.1416 \cdot (110000Pa - 100000Pa)})}^{\frac{1}{3}}

Next Step Prepare to Evaluate

∴

h = {(\frac{0.18 \cdot 6 \cdot 1.02 \cdot \ln (\frac{0.05}{0.04})}{3.1416 \cdot (110000 - 100000)})}^{\frac{1}{3}}

Next Step Evaluate

∴

h = 0.0198526947502211m

Next Step Convert to Output's Unit

∴

h = 1.98526947502211cm

LAST Step Rounding Answer

∴

h = 1.9853cm

How to Evaluate Gap spacing?

Gap spacing evaluator uses Gap Spacing = ((Flow Rate of the Electrolyte*6*Dynamic Viscosity*ln(Radius of the Electrodes/Radius of Flushing Hole))/(pi*(Pressure in Flushing Hole-Atmospheric Pressure)))^(1/3) to evaluate the Gap Spacing, The Gap spacing formula is defined as the width of distance between electrode and work during EDM. It is usually very less than radius of the flushing hole. Gap Spacing is denoted by h symbol.

How to evaluate Gap spacing using this online evaluator? To use this online evaluator for Gap spacing, enter Flow Rate of the Electrolyte (Q), Dynamic Viscosity (μ_v), Radius of the Electrodes (R₀), Radius of Flushing Hole (R₁), Pressure in Flushing Hole (P₁) & Atmospheric Pressure (P_atm) and hit the calculate button.

FAQs on Gap spacing

What is the formula to find Gap spacing?

The formula of Gap spacing is expressed as Gap Spacing = ((Flow Rate of the Electrolyte*6*Dynamic Viscosity*ln(Radius of the Electrodes/Radius of Flushing Hole))/(pi*(Pressure in Flushing Hole-Atmospheric Pressure)))^(1/3). Here is an example- 198.5269 = ((0.18*6*1.02*ln(0.05/0.04))/(pi*(110000-100000)))^(1/3).

How to calculate Gap spacing?

With Flow Rate of the Electrolyte (Q), Dynamic Viscosity (μ_v), Radius of the Electrodes (R₀), Radius of Flushing Hole (R₁), Pressure in Flushing Hole (P₁) & Atmospheric Pressure (P_atm) we can find Gap spacing using the formula - Gap Spacing = ((Flow Rate of the Electrolyte*6*Dynamic Viscosity*ln(Radius of the Electrodes/Radius of Flushing Hole))/(pi*(Pressure in Flushing Hole-Atmospheric Pressure)))^(1/3). This formula also uses Archimedes' constant and Natural Logarithm (ln) function(s).

Can the Gap spacing be negative?

No, the Gap spacing, measured in Length cannot be negative.

Which unit is used to measure Gap spacing?

Gap spacing is usually measured using the Centimeter[cm] for Length. Meter[cm], Millimeter[cm], Kilometer[cm] are the few other units in which Gap spacing can be measured.
