Air infiltration rate into room (CFM) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Air Infiltration Rate into Room = Number of air changes per hour*(Room Volume/60)
CFM = ACH*(V/60)
This formula uses 3 Variables

Variables Used

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.
Number of air changes per hour - Number of air changes per hour is a measure of the air volume added to or removed from a space in one hour, divided by the volume of the space.
Room Volume - (Measured in Cubic Meter) - Room volume is volume of the conditioned space under study or under consideration.

STEP 1: Convert Input(s) to Base Unit

Number of air changes per hour: 16 --> No Conversion Required
Room Volume: 400 Cubic Foot --> 11.3267386369359 Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

CFM = ACH*(V/60) --> 16*(11.3267386369359/60)

Evaluating ... ...

CFM = 3.02046363651624

STEP 3: Convert Result to Output's Unit

3.02046363651624 Cubic Meter per Second -->6399.99999999999 Cubic Foot per Minute (Check conversion here)

FINAL ANSWER

6399.99999999999 ≈ 6400 Cubic Foot per Minute <-- Air Infiltration Rate into Room

(Calculation completed in 00.004 seconds)
