Sensible Cooling Load due to infiltrating air Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sensible Cooling Load = 1.1*Air Infiltration Rate into Room*Temperature Change Between Outdoor and Inside Air
Q_ph = 1.1*CFM*TC
This formula uses 3 Variables

Variables Used

Sensible Cooling Load - (Measured in Watt) - Sensible Cooling Load is the heat added or removed from conditioned space by means of roof, ceiling, floor or windows.
Air Infiltration Rate into Room - (Measured in Cubic Meter per Second) - Air Infiltration Rate into Room is the volumetric flow rate of outside air into a building/room.
Temperature Change Between Outdoor and Inside Air - (Measured in Kelvin) - Temperature change between outdoor and inside air is the temperature difference between air outdoor and inside of the specified space.

STEP 1: Convert Input(s) to Base Unit

Air Infiltration Rate into Room: 6400 Cubic Foot per Minute --> 3.02046363651624 Cubic Meter per Second (Check conversion here)
Temperature Change Between Outdoor and Inside Air: 12 Fahrenheit --> 262.038882255554 Kelvin (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_ph = 1.1*CFM*TC --> 1.1*3.02046363651624*262.038882255554

Evaluating ... ...

Q_ph = 870.626806726888

STEP 3: Convert Result to Output's Unit

870.626806726888 Watt -->2972.69076141014 Btu (th) per Hour (Check conversion here)

FINAL ANSWER

2972.69076141014 ≈ 2972.691 Btu (th) per Hour <-- Sensible Cooling Load

(Calculation completed in 00.004 seconds)
