Here is how the Reliability Number equation looks like.

2 = 100 - ((\frac{98}{100}) \cdot 100)

2 = 100 - ((\frac{98}{100}) \cdot 100)

2 = 100 - ((\frac{98}{100}) \cdot 100)

Reliability Number Solution

Follow our step by step solution on how to calculate Reliability Number?

FIRST Step Consider the formula

RN = 100 - ((\frac{D}{T u}) \cdot 100)

Next Step Substitute values of Variables

∴

RN = 100 - ((\frac{98}{100}) \cdot 100)

Next Step Prepare to Evaluate

∴

RN = 100 - ((\frac{98}{100}) \cdot 100)

LAST Step Evaluate

∴

RN = 2

Note: Value should be greater than 0.

Formulas to find Defective Units

Tested Units

The Tested Units refer to the number of units or objects tested for conducting the sampling.

Symbol: T_u

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Tested Units

Other formulas in Quality Control in Construction category

Go Number of Defective Units given Reliability Number

D = (100 - RN) \cdot \frac{T u}{100}

Go Number of Units Tested given Reliability Number

T u = \frac{100 \cdot D}{100 - RN}

Go Coefficient of Variation

V = σ \cdot \frac{100}{AM}

Go Proportion Non-Confirming in Sample

P = \frac{nP}{n}

How to Evaluate Reliability Number?

Reliability Number evaluator uses Reliability Number = 100-((Defective Units/Tested Units)*100) to evaluate the Reliability Number, The Reliability Number formula is defined as the overall measurement of consistency or reliability is a measure of how well a product will perform under a certain set of conditions for a specified amount of time. Reliability Number is denoted by RN symbol.

How to evaluate Reliability Number using this online evaluator? To use this online evaluator for Reliability Number, enter Defective Units (D) & Tested Units (T_u) and hit the calculate button.

FAQs on Reliability Number

What is the formula to find Reliability Number?

The formula of Reliability Number is expressed as Reliability Number = 100-((Defective Units/Tested Units)*100). Here is an example- 2 = 100-((98/100)*100).

How to calculate Reliability Number?

With Defective Units (D) & Tested Units (T_u) we can find Reliability Number using the formula - Reliability Number = 100-((Defective Units/Tested Units)*100).
