Latent cooling load from ventilation air Solution

STEP 0: Pre-Calculation Summary
Formula Used
Latent cooling load from ventilation air in BTU/hr = 0.68*Air ventilation rate in Cubic foot per minute*(Outside Humidity Ratio-Inside humidity ratio)
QL = 0.68*CFM*(W'o-W'i)
This formula uses 4 Variables
Variables Used
Latent cooling load from ventilation air in BTU/hr - Latent cooling load from ventilation air in BTU/hr is the heat the results from an increase or decrease in the amount of moisture held by the air.
Air ventilation rate in Cubic foot per minute - Air ventilation rate in Cubic foot per minute is the amount of air inhaled in a specified time period (eg. per minute) and it is also called breathing rate and inhalation rate.
Outside Humidity Ratio - Outside Humidity Ratio is the ratio of the weight of water vapor contained outside the room compared to the weight of the dry air outside the same room.
Inside humidity ratio - Inside humidity ratio is is the ratio of the weight of water vapor contained inside the room compared to the weight of the dry air inside the same room.
STEP 1: Convert Input(s) to Base Unit
Air ventilation rate in Cubic foot per minute: 25 --> No Conversion Required
Outside Humidity Ratio: 95 --> No Conversion Required
Inside humidity ratio: 60 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
QL = 0.68*CFM*(W'o-W'i) --> 0.68*25*(95-60)
Evaluating ... ...
QL = 595
STEP 3: Convert Result to Output's Unit
595 --> No Conversion Required
FINAL ANSWER
595 <-- Latent cooling load from ventilation air in BTU/hr
(Calculation completed in 00.004 seconds)

3 Latent Cooling Load and Heat Gain Calculators

Latent cooling load from ventilation air
Go Latent cooling load from ventilation air in BTU/hr = 0.68*Air ventilation rate in Cubic foot per minute*(Outside Humidity Ratio-Inside humidity ratio)
Latent Heat Gain per person using Latent Heat Gain from people
Go Latent heat gains per person = Latent Heat Gain/Number of people
Latent Heat Gain from people
Go Latent Heat Gain = Latent heat gains per person*Number of people

Latent cooling load from ventilation air Formula

Latent cooling load from ventilation air in BTU/hr = 0.68*Air ventilation rate in Cubic foot per minute*(Outside Humidity Ratio-Inside humidity ratio)
QL = 0.68*CFM*(W'o-W'i)

What is the difference between total cooling and sensible cooling?

Valuable cooling capacity is lost and the air conditioning unit works less efficiently. The entire sum of cooling capacity generated is known as the total cooling capacity. The proportion that is used for purposely cooling the air is called sensible cooling capacity.

How to Calculate Latent cooling load from ventilation air?
