1 Explain that a population pyramid shows the age and sex structure of a population. 2  Point to the horizontal bars, which show the percentage (or the absolute number) of males and females in each age group. 3  Have students interpret the chart.
1 Although they range from $150-$400 or more, a large capacity (25-70 pints) dehumidifier for a basement (the dampest portion of most homes) or other large area averages $200-$300.
How much does a dehumidifier cost to run? From my experience of using several models, the power consumption varies from 100 watts (10l/day models) to 160 watts (my Amcor DC930-H rated at 15l/day) measured using a watt meter.m x 4m x 2.5m room I have an Amcor DC930-H (15l/day rating) located, with the door closed and starting at 72% RH, it goes as follows: It will bring the humidity down to about 65% after 15 minutes, 60% after an hour, around 55% after two hours and 50% after about 8 hours of continuous operation.
