Basic Statistics for Epidemiology: Prevalence vs Incidence. In short, epidemiology is sort of the who what, when, why, how and where of disease. It doesnât involve any experimentation or clinical trials, so it is really of interest to public health, because it is just about what happens.
So if a queen-sized waterbed with a bladder-type mattress holds roughly 130 gallons of water that weighs in at 1,084 pounds plus the weight of the frame and two people.o keep the math simple let s assume that the mattress, frame and two adults weighs 1,300 pounds and that the bed assembly measures six feet by six feet taking up a total of 36 square feet of floor space. If we divide the weight of the bed by 36 the square footage-that gets us to 36 pounds per square foot.
So youâve probably heard about waterbeds and how they can enhance your sleeping experience dramatically, however, many people still have doubts about whether or not they are right for them. Many people fear the weight of a waterbed will crash through the bedroom floor itâs resting on. While this may be a fear of yours, in most instances it shouldnât be. Perhaps one of the most widely asked questionsâ concerning waterbeds is if their floors can handle the weight of a waterbed?
