Measuring a swimming pool is necessary for two reasons. The first is to calculate the water volume in the pool. You will use this number frequently when adding chemicals to the pool water as many of the chemicals depend on the amount of water in the pool. The second reason for measuring ...
Chemicals can be loosely divided into two extremes: acids and bases. The pH scale measures exactly where a chemical falls between one of those two extremes. The scale measures 0 to 14; the lower the number, the more acidic a substance is. Water, for example, has a pH of 7 and is con...
Surface area is an important measurement that comes into play when you want to calculate water volume, or when buying a swimming pool cover. It is easy enough to calculate the surface area of a round, square or rectangular pool, but a little tricky with an irregular, curved pool. Rectangula...
Watch this science video tutorial from Nurd Rage on how to make a chemiluminescent reaction with home chemicals. Make a chemiluminescent singlet oxygen red light pulse from two simple chemicals almost anyone can buy: pool chlorine and hydrogen peroxide. ...
It’s obvious that Hilary needed to stock up on pool chemicals and purchase the right equipment, but all of that would sit idle without a full schedule of customers whose pools need regular attention. While digital ads are an important part of the customer journey, you must support them with...
The pump should never have a rate of flow per hour greater than the capacity of the pond, but it should be able to circulate nearly half the pool's water per hour. To calculate the approximate volume of your pool, multiply its length by its width by its depth (in inches). This ...
Pool and spa maintenance: Cubic feet are used to calculate the volume of water in swimming pools and spas, and to determine the number of chemicals needed to maintain water quality. Brewing and winemaking: Cubic feet are used to calculate the volume of ingredients and final product in brewing...
Designthe drivewayusing a piece of graph paper and a pencil. Draw the driveway to scale so that you can calculate the area you need to cover and purchase enough stones. Work out the area by multiplying the length of the driveway by the width of the driveway. ...
Sodium chlorite is used commercially to bleach fabrics and paper and to purify and disinfect municipal water. Homeowners use sodium chlorite as an anti-fouling agent for water and a precursor for other flammable or explosive chemicals. There are many different ways to make sodium chlorite. Commercia...
It enables companies to calculate the PCFs of their chemical materials more precisely in a way that is harmonized across the industry, while remaining fully compliant with less specific international standards for GHG accounting. The PCF Guideline is open source. Did you enjoy this session? If ...
