Energy Conversion Efficiency of Solar Chimney Solution

STEP 0: Pre-Calculation Summary
Formula Used
Max Efficiency of a Solar Chimney = 9.81*Height of Chimney/(1005*Ambient Air Temperature)
ηmax = 9.81*H/(1005*Ta)
This formula uses 3 Variables
Variables Used
Max Efficiency of a Solar Chimney - Max Efficiency of a Solar Chimney is defined as the maximum efficiency that can be obtained from a solar chimney. It is directly dependent on the height of the chimney.
Height of Chimney - (Measured in Meter) - The Height of Chimney is defined as the height of the chimney tower form the metal frame above the ground.
Ambient Air Temperature - (Measured in Kelvin) - Ambient Air Temperature is the temperature where the ramming process starts.
STEP 1: Convert Input(s) to Base Unit
Height of Chimney: 2 Meter --> 2 Meter No Conversion Required
Ambient Air Temperature: 300 Kelvin --> 300 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ηmax = 9.81*H/(1005*Ta) --> 9.81*2/(1005*300)
Evaluating ... ...
ηmax = 6.50746268656716E-05
STEP 3: Convert Result to Output's Unit
6.50746268656716E-05 --> No Conversion Required
FINAL ANSWER
6.50746268656716E-05 6.5E-5 <-- Max Efficiency of a Solar Chimney

Angle of incidence of sun rays
Go Angle Of Incidence = acos(sin(Latitude Angle)*(sin(Declination Angle)*cos(Tilt Angle)+cos(Declination Angle)*cos(Surface Azimuth Angle)*cos(Hour angle)*sin(Tilt Angle))+cos(Latitude Angle)*(cos(Declination Angle)*cos(Hour angle)*cos(Tilt Angle)-sin(Declination Angle)*cos(Surface Azimuth Angle)*sin(Tilt Angle))+cos(Declination Angle)*sin(Surface Azimuth Angle)*sin(Hour angle)*sin(Tilt Angle))
Hour Angle at Sunrise and Sunset
Go Hour angle = acos(-tan(Latitude Angle-Tilt Angle)*tan(Declination Angle))
Daylight Hours
Go Daylight Hours = 3600*acos(-tan(Latitude Angle)*tan(Declination Angle))
Tilt factor for reflected radiation
Go Tilt factor for reflected radiation = (Reflectivity*(1-cos(Tilt Angle)))/2
Energy Conversion Efficiency of Solar Chimney
Go Max Efficiency of a Solar Chimney = 9.81*Height of Chimney/(1005*Ambient Air Temperature)
Tilt factor for diffused radiation
