Latent Heat Gain from people Solution

STEP 0: Pre-Calculation Summary

Formula Used

Latent Heat Gain = Latent heat gains per person*Number of people
Q_l = q_l*n
This formula uses 3 Variables

Variables Used

Latent Heat Gain - (Measured in Watt) - Latent Heat Gain is the heat that results from an increase or decrease in the amount of moisture held by the air.
Latent heat gains per person - (Measured in Watt) - Latent heat gains per person is the heat that results from an increase or decrease by per person, in the amount of moisture held by the air.
Number of people - Number of people is the count of people responsible for heat gain in space.

STEP 1: Convert Input(s) to Base Unit

Latent heat gains per person: 10 Btu (th) per Hour --> 2.928749999929 Watt (Check conversion here)
Number of people: 70 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_l = q_l*n --> 2.928749999929*70

Evaluating ... ...

Q_l = 205.01249999503

STEP 3: Convert Result to Output's Unit

205.01249999503 Watt -->700 Btu (th) per Hour (Check conversion here)

FINAL ANSWER

700 Btu (th) per Hour <-- Latent Heat Gain

(Calculation completed in 00.004 seconds)

Latent Heat Gain from people Formula

Latent Heat Gain = Latent heat gains per person*Number of people
Q_l = q_l*n

What is the heat load of a person?

In terms of heat units, one calorie equals about 4 Btu's. This process of internal heat generation is called metabolism. At the outset, we stated that the people load was usually taken to be about 400 Btu's per person, but this is only true for a person sitting at rest.
