Maintenance Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maintenance Factor = Final Illumination/Initial Illumination
MF = I_final/I_initial
This formula uses 3 Variables

Variables Used

Maintenance Factor - Maintenance factor refers to a multiplier or percentage used to adjust the initial illumination levels of a lighting system to account for degradation and dirt accumulation over time.
Final Illumination - (Measured in Lux) - Final illumination refers to the level of light or brightness achieved in a particular space or area after all lighting fixtures and sources have been installed and turned on.
Initial Illumination - (Measured in Lux) - Initial illumination refers to the starting level of light in a given area when the lighting fixtures are initially turned on before any adjustments or changes are made.

STEP 1: Convert Input(s) to Base Unit

Final Illumination: 6.2 Lux --> 6.2 Lux No Conversion Required
Initial Illumination: 3.1 Lux --> 3.1 Lux No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

MF = I_final/I_initial --> 6.2/3.1

Evaluating ... ...

MF = 2

STEP 3: Convert Result to Output's Unit

2 --> No Conversion Required

FINAL ANSWER

2 <-- Maintenance Factor

Number of Lamps Required for Illumination

LaTeX Go Number of Lamp = (Illumination Intensity*Area of Illumination)/(Luminous Flux*Utilization Factor*Maintenance Factor)

Reduction Factor

LaTeX Go Reduction Factor = Mean Spherical Candle Power/Mean Horizontal Candle Power

Solid Angle

LaTeX Go Solid Angle = Area of Illumination/(Radius of Illumination^2)

Mean Spherical Candle Power

LaTeX Go Mean Spherical Candle Power = Luminous Flux/(4*pi)

Maintenance Factor Formula

LaTeX Go

Maintenance Factor = Final Illumination/Initial Illumination
MF = I_final/I_initial

Why is Maintenance Factor used?

Maintenance Factor is used to determine depreciation of a lamp or a reflective surface over a period of a time.

How to Calculate Maintenance Factor?

Maintenance Factor calculator uses Maintenance Factor = Final Illumination/Initial Illumination to calculate the Maintenance Factor, The Maintenance Factor formula is defined as the ratio between the illumination under normal working conditions to the illumination when everything is clean. Maintenance Factor is denoted by MF symbol.

How to calculate Maintenance Factor using this online calculator? To use this online calculator for Maintenance Factor, enter Final Illumination (I_final) & Initial Illumination (I_initial) and hit the calculate button. Here is how the Maintenance Factor calculation can be explained with given input values -> 1.935484 = 6.2/3.1.

FAQ

What is Maintenance Factor?

The Maintenance Factor formula is defined as the ratio between the illumination under normal working conditions to the illumination when everything is clean and is represented as MF = I_final/I_initial or Maintenance Factor = Final Illumination/Initial Illumination. Final illumination refers to the level of light or brightness achieved in a particular space or area after all lighting fixtures and sources have been installed and turned on & Initial illumination refers to the starting level of light in a given area when the lighting fixtures are initially turned on before any adjustments or changes are made.

How to calculate Maintenance Factor?

The Maintenance Factor formula is defined as the ratio between the illumination under normal working conditions to the illumination when everything is clean is calculated using Maintenance Factor = Final Illumination/Initial Illumination. To calculate Maintenance Factor, you need Final Illumination (I_final) & Initial Illumination (I_initial). With our tool, you need to enter the respective value for Final Illumination & Initial Illumination and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
