Слайд 1

Слайд 2

Objective To compare the percent of air humidity at any place’s and to grasp the reason of air differe nce

Слайд 3

Tasks To study the concept “humidity” and its meaning To study the device for measuring of humidity To create the device for measuring of humidity at room To measure the air humidity at different place’s

Слайд 4

What is humidity? All living things of our planet need air

Слайд 5

Classification of humidity Until 55% - dry From 56% to 70% - moderately dry From 85% - higher moist

Слайд 6

A healthy human feels comfortable in the hamidity range of 30% to 60%

Слайд 7

Hygrometer Topics : 1) Weight 2) Hair 3) Electrical 4) Ceramic 5) Condensation

Слайд 9

Psychrometer Topics : 1) Station 2) Remote 3) Aspiration

Слайд 11

What will we need to create the psychrometer ? Two room thermometers Ampoule with distilled water Bandage/cloth Box Scotch Scissors Psychometric table

Слайд 12

To glue first thermometer to the bottom of our box

Слайд 13

To bind the bandage to the end of second thermometer

Слайд 14

To glue the second thermometer nearly first

Слайд 15

To pass the bandage to ampoule that it will concern the water

Слайд 16

We’ve got “dry” and “wet” thermometers

Слайд 17

To take the testimony

Слайд 18

To measure the humidity Place Dry thermometer Wet thermometer Difference Percent of humidity Bathroom 25 22 3 77% Kitchen 28 24 4 72% Balcony 6 4 2 73% My room before aeration 24 21 3 77% My room after aeration 21 15 6 52% We need to take the testimony from dry and wet thermometers than to determine the relative humidity for psychrometric table
