Equivalent Diameter of fin channel Solution

Follow our step by step solution on how to calculate Equivalent Diameter of fin channel?

FIRST Step Consider the formula

d e = \frac{4 \cdot (W \cdot L - δ f \cdot L f)}{2 \cdot (W + L f)}

Next Step Substitute values of Variables

∴

d e = \frac{4 \cdot (30mm \cdot 15mm - 4mm \cdot 12mm)}{2 \cdot (30mm + 12mm)}

Next Step Convert Units

∴

d e = \frac{4 \cdot (0.03m \cdot 0.015m - 0.004m \cdot 0.012m)}{2 \cdot (0.03m + 0.012m)}

Next Step Prepare to Evaluate

∴

d e = \frac{4 \cdot (0.03 \cdot 0.015 - 0.004 \cdot 0.012)}{2 \cdot (0.03 + 0.012)}

Next Step Evaluate

∴

d e = 0.0191428571428571m

Next Step Convert to Output's Unit

∴

d e = 19.1428571428571mm

LAST Step Rounding Answer

∴

d e = 19.1429mm
