Beth n Rod 1,279 Report post Posted March 31, 2003 Written by Ron P. ----------------------------------------------------------------------- When it come to ratios, it makes no diffrence if your talking about 1 oz. or 100000000 lbs. because the ratio stays the same. Example: 1 oz of chem to 5 oz of water is 1 to 5 or, 5 oz chem to 1oz of water is 5 to 1 Now this is the tricky part that a lot of people get messed up on. Don't confuse weight and volume. There is a big difference. When you buy a powdered chem and it tells you to mix 8 oz of chem to 1 gal of water, some people would use a measuring cup and a 5 gal bucket. This would be WRONG. WHY??? Well... Water is measured by volume (in this case), dry chem is measured by weight. They're two diffrent things. What weighs more, one lb. of feather's or one lb. of gold? Both weigh the same but the feather's will take up more volume. Many guys who use powdered chems don't have a scale. Then they wonder why other people love a chem that they can't get to work very well. A good example of problems stemming from a mis-informed pressure washer would be when they use a X-JET. Everyone tells the next guy how they mix their chemicals and how they work. Well, guy A is telling guy B to mix 1 gal of chem to 4 gal of water and use his x-jet to apply. Well guy A has a 3 gal per min wash unit and guy B has a 5 gal per min unit. They will have diffrent DRAW RATES AND WON'T WORK THE SAME WAY. Guy B will need to almost double the amount of chemicals. He is shooting almost twice the amount of water in the same minute. Next are the guys who only use water to keep their deck cleaners/strippers wet. This just deluites the cleaner. You must keep it wet with MORE CHEMICAL. RATIO "a way of concisely showing the realationship between two quantities of something". Here's another example of a ratio. Say your downstreamer has a draw rate of 20 %. Let's also say you have a 5 gal per min pump. In one min you pumped 5 gal of water and added 20% chem. Twenty percent (20%) of 5 gal per min would be 1 gallon, so you had a 5 to 1 ratio. The pump pumped 5 gal and drew in 1 gal so a total of 6 gal shot out the tip in one min. 5 to 1 makes 6 total. Most people dont understand how you can get 6 gal per min from a 5 gal per min pump but it will.[draw rate] Now have I helped you or just messed you all up?
