Effective Cover given Shortest Distance Solution

Follow our step by step solution on how to calculate Effective Cover given Shortest Distance?

FIRST Step Consider the formula

d' = \sqrt{{(acr + (\frac{D}{2}))}^{2} - {(\frac{z}{2})}^{2}}

Next Step Substitute values of Variables

∴

d' = \sqrt{{(2.51cm + (\frac{0.5m}{2}))}^{2} - {(\frac{40A}{2})}^{2}}

Next Step Convert Units

∴

d' = \sqrt{{(0.0251m + (\frac{0.5m}{2}))}^{2} - {(\frac{4E-9m}{2})}^{2}}

Next Step Prepare to Evaluate

∴

d' = \sqrt{{(0.0251 + (\frac{0.5}{2}))}^{2} - {(\frac{4E-9}{2})}^{2}}

Next Step Evaluate

∴

d' = 0.2751m

LAST Step Convert to Output's Unit

∴

d' = 275.1mm
