How many pounds of ferric chloride are in 250 gallons of 22% strength? (Assume the specific gravity is 1.41) Chemical A is what percent heavier than chemical B? online calculator and figures and tables with water properties like density, specific weight and thermal expansion coefficient of liquid water at temperatures ranging 0 to 360☌ (32 to 680☏). How much does 45 gallons of 25% Alum weigh if the specific gravity is 1.35?įerric chloride weighs 14.25 lbs/gal. How many pounds of the 50 gallons are available chlorine? What is the weight difference between 75 gallons of water and 42 gallons of sodium hypochlorite with a specific gravity of 1.42?Ī treatment operator has 50 gallons of 12.5% sodium hypochlorite. What is the corresponding weight in pounds per gallon?Ĭhlorine gas has formed into a liquid state. Liquid sodium hypochlorite has a specific gravity of 1.47. Solve the following density related problems. On any State exam, you will be given the specific gravity or corresponding weight of the substance in the question. Remember, these are only examples and should not be put to memory. The table below lists common specific gravities/densities and weight of substances used in the waterworks industry. Conversely, if a substance has a specific gravity greater than 1, it will sink in water. Comparing to water, whose density is 1.00 g/ml, cooking oil is less dense. The range is from 0.91 to 0.93 g/cm 3 between the temperatures of 15 ☌ and 25 ☌. The density of the oils varies with each type and temperature. For example, if something has a specific gravity less than water (<1), then the substance will float on water. Just like sunflower oil, it is considered a semidrying oil and has a variety of industrial uses. When discussing specific gravity, many things are compared to water. This is also referred to as specific gravity.

The density (mass per unit volume) of water is 1.00. So, how much does water actually weigh? There are a few variables, such as temperature, that determine the weight of water, but for all practical purposes in waterworks mathematics, water weighs 8.34 pounds per gallon. It makes up approximately 60% of our total body weight and as much as 75% of the earth’s surface. Water is essential for the survival of all life forms.
