Equivalent Diameter for Square Pitch in Heat Exchanger Solution

Follow our step by step solution on how to calculate Equivalent Diameter for Square Pitch in Heat Exchanger?

FIRST Step Consider the formula

D e = (\frac{1.27}{D Outer}) \cdot (({P Tube}^{2}) - 0.785 \cdot ({D Outer}^{2}))

Next Step Substitute values of Variables

∴

D e = (\frac{1.27}{19mm}) \cdot (({23mm}^{2}) - 0.785 \cdot ({19mm}^{2}))

Next Step Convert Units

∴

D e = (\frac{1.27}{0.019m}) \cdot (({0.023m}^{2}) - 0.785 \cdot ({0.019m}^{2}))

Next Step Prepare to Evaluate

∴

D e = (\frac{1.27}{0.019}) \cdot (({0.023}^{2}) - 0.785 \cdot ({0.019}^{2}))

Next Step Evaluate

∴

D e = 0.0164174236842105m

Next Step Convert to Output's Unit

∴

D e = 16.4174236842105mm

LAST Step Rounding Answer

∴

D e = 16.4174mm
