Useful heat gain in concentrating collector Solution

STEP 0: Pre-Calculation Summary

Formula Used

Useful Heat Gain = Effective Area of Aperture*Solar Beam Radiation-Heat Loss from Collector
q_u = A_a*S-q_l
This formula uses 4 Variables

Variables Used

Useful Heat Gain - (Measured in Watt) - Useful heat gain is defined as the rate of heat transfer to the working fluid.
Effective Area of Aperture - (Measured in Square Meter) - Effective area of aperture is defined as total area of aperture exposed to the incident radiation.
Solar Beam Radiation - (Measured in Watt per Square Meter) - Solar beam radiation is the amount of radiation absorbed in the absorber per unit effective aperture area.
Heat Loss from Collector - (Measured in Watt) - Heat loss from collector is defined as the heat losses that occur due to convection, conduction and radiation.

STEP 1: Convert Input(s) to Base Unit

Effective Area of Aperture: 44.91 Square Meter --> 44.91 Square Meter No Conversion Required
Solar Beam Radiation: 82.56 Joule per Second per Square Meter --> 82.56 Watt per Square Meter (Check conversion here)
Heat Loss from Collector: 8 Watt --> 8 Watt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

q_u = A_a*S-q_l --> 44.91*82.56-8

Evaluating ... ...

q_u = 3699.7696

STEP 3: Convert Result to Output's Unit

3699.7696 Watt --> No Conversion Required

FINAL ANSWER

3699.7696 ≈ 3699.77 Watt <-- Useful Heat Gain
