Q_L = 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 - (Measured in Cubic Meter per Second) - 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: 25 Cubic Foot per Minute --> 0.0117986860801416 Cubic Meter per Second (Check conversion here)
Outside Humidity Ratio: 95 --> No Conversion Required
Inside Humidity Ratio: 60 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_L = 0.68*CFM*(W'_o-W'_i) --> 0.68*0.0117986860801416*(95-60)

Evaluating ... ...

Q_L = 0.28080872870737

STEP 3: Convert Result to Output's Unit

0.28080872870737 --> No Conversion Required

FINAL ANSWER

0.28080872870737 ≈ 0.280809 <-- Latent Cooling Load from Ventilation Air in BTU/hr

Latent Cooling Load from Ventilation Air in BTU/hr = 0.68*Air Ventilation Rate*(Outside Humidity Ratio-Inside Humidity Ratio)
Q_L = 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.
