Answer:
<em>The contribution of people to the cooling load of the store is 19722.5 W</em>
Explanation:
Total amount of customers = 225
Total amount of employees = 20
Total amount of people in the store at that instant n = 245 people
Average rate of heat generation Q = 115 W
percentage of these heat generated that is sensible heat = 70%
Sensible heat raises the surrounding temperature. Latent heat only causes a change of state.
The total heat generated by all the people in the store = n x Q
==> 245 x 115 = 28175 W
but only 70% of this heat is sensible heat that raises the temperature of the store, therefore, the contribution of people to the cooling load of the store = 70% of 28175 W
==> 0.7 x 28175 = <em>19722.5 W</em>
Answer:
Explanation:
12 ÷ 5 = 2.4
2.4 x 6 = 14.4 = 15 days or 14 days and 4 hours
