Cooling load for roof, wall or glass given Corrected Cooling Load Temperature Difference Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cooling Load = Overall Heat Transfer Coefficient*Area of Roof*Corrected Cooling Load Temperature Difference
Q = U_o*A_r*CLTD_c
This formula uses 4 Variables

Variables Used

Cooling Load - (Measured in Watt) - Cooling load is the amount of heat that must be removed.
Overall Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - The Overall Heat Transfer Coefficient is a measure of the overall ability of a series of conductive and convective barriers to transfer heat.
Area of Roof - (Measured in Square Meter) - Area of roof is the length into breadth of room under study.
Corrected Cooling Load Temperature Difference - (Measured in Kelvin) - Corrected cooling load temperature difference is the actual temperature difference between the outdoor and indoor air.

STEP 1: Convert Input(s) to Base Unit

Overall Heat Transfer Coefficient: 0.25 Watt per Square Meter per Kelvin --> 0.25 Watt per Square Meter per Kelvin No Conversion Required
Area of Roof: 5600 Square Foot --> 520.257024004163 Square Meter (Check conversion here)
Corrected Cooling Load Temperature Difference: 13 Fahrenheit --> 262.594437837601 Kelvin (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = U_o*A_r*CLTD_c --> 0.25*520.257024004163*262.594437837601

Evaluating ... ...

Q = 34154.1501873591

STEP 3: Convert Result to Output's Unit

34154.1501873591 Watt -->116538.79779839 Btu (IT) per Hour (Check conversion here)

FINAL ANSWER

116538.79779839 ≈ 116538.8 Btu (IT) per Hour <-- Cooling Load

(Calculation completed in 00.004 seconds)
