Mean Horizontal Candle Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mean Horizontal Candle Power = Sum of Candle Power/Number of Lamp
M.H.C.P. = S/N_Lamp
This formula uses 3 Variables

Variables Used

Mean Horizontal Candle Power - (Measured in Candela) - Mean Horizontal Candle Power is a measure that represents the average intensity of light emitted by a source along the horizontal plane.
Sum of Candle Power - (Measured in Candela) - Sum of candle power refers to the total luminous intensity or combined light output from multiple light sources or individual lamps within a lighting system or installation. It is denoted as CP.
Number of Lamp - Number of lamps refers to the quantity of individual light sources used in a lighting system. It represents the count of separate lamps employed to provide illumination in a given space.

STEP 1: Convert Input(s) to Base Unit

Sum of Candle Power: 7.65 Candela --> 7.65 Candela No Conversion Required
Number of Lamp: 3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M.H.C.P. = S/N_Lamp --> 7.65/3

Evaluating ... ...

M.H.C.P. = 2.55

STEP 3: Convert Result to Output's Unit

2.55 Candela --> No Conversion Required

FINAL ANSWER

2.55 Candela <-- Mean Horizontal Candle Power

< 15 Illumination Parameters Calculators

Number of Lamps Required for Illumination

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

Index of Refraction

Go Refractive Index of Medium 1 = (Refractive Index of Medium 2*sin(Refracted Angle))/sin(Incident Angle)

Luminance

Go Luminance = Luminous Intensity/(Area of Illumination*cos(Illumination Angle))

Luminous Flux

Go Luminous Flux = (Area of Illumination*Luminous Intensity)/(Length of Illumination^2)

Reduction Factor

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

Mean Horizontal Candle Power

Go Mean Horizontal Candle Power = Sum of Candle Power/Number of Lamp

Solid Angle

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

Maintenance Factor

Go Maintenance Factor = Final Illumination/Initial Illumination

Illumination

Go Illumination Intensity = Luminous Flux/Area of Illumination

Mean Hemi-Spherical Candle Power

Go Mean Hemi Spherical Candle Power = Luminous Flux/(2*pi)

Mean Spherical Candle Power

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

Lamp Efficiency

Go Lamp Efficiency = Luminous Flux/Input Power

Candle Power

Go Candle Power = Luminous Flux/Solid Angle

Lumens

Go Lumen = Candle Power*Solid Angle

Depreciation Factor

Go Depreciation Factor = 1/Maintenance Factor

Mean Horizontal Candle Power Formula

Mean Horizontal Candle Power = Sum of Candle Power/Number of Lamp
M.H.C.P. = S/N_Lamp
