Panel Impact Ratio: Video Tutorial

[@AdamosGarage]

Great explanation Steve!! I always thought we had to empty the cannon completely! This is much easier & quicker!! Thank you!!

[@StevePierson123]

@@AdamosGarage Thank you Adamo! Emptying the cannon is intuitive which is why it’s done, but there can be a bit of error especially with opaque bottles. Once we remember that 1 gram = 1 ml of water, measuring becomes a lot easier. There are still some shortcuts to this video (like taring the scale with the bucket on it) but I didn’t include it because some battery powered scales automatically shut off and can lose the measurement.

[@AMI_Detail]

That is the EASIEST and MOST ACCURATE way to measure total foam cannon output that I've seen. Thanks to help simplify and demystify that part of PIR calculations. Feel free to use anything from the PIR / Dilution Ratio spreadsheet that you might find useful. I would suggest one more scenario that would let you enter the dilution ratio, 10:1 for example, to get the ADJUSTED amount of product required to meet the company's recommended mixture.

@@AMI_Detail thank you! I appreciate you sharing your work with me. I’m a big fan of “free and open source”. I like the way you handled ratios in your sheet, this is the first revision so I’m open to suggestions. Will definitely look into this 👍

Very good tutorial

Nice video Steve! Stuff like that always went over my head and that was the first time I could wrap my head around what PIR is and how to calculate it. But what benefit does knowing provide?

[@StevePierson123]

@@attention2detailswchelsea it would benefit suppliers and detailers. PIR eliminates most of the variables leading up to the barrel of the cannon. This means regardless of the combination of pressure washer, foam cannon brand, etc… running a 1% PIR on a Kranzle vs 1% on a Ryobi would net a similar foaming experience. For manufacturers, they would no longer need to give a range (ex. 1-4oz in a foam cannon) that we need to figure out. Suppliers could just give a single PIR and that would put the detailer very close to the foaming sweet spot.

@@FrankoDetails but 1st in our hearts… hahaha thank you Franko! Yeah listening to that noise through the headphone made me want to go 🤣

[@AMI_Detail]

@FrankoDetails And here I was thinking... How did Steve know I was watching during a "bathroom break?" Actually... I was cooking supper and missed the water flow sound of the pressure gun emptying into the reservoir. He got an extra view as I had to roll it again to get the full effect.

1:20 - Just as I expected... Not just ANY Zebra G2, but the EXTRA FINE 0.5mm tip. Watch out, Steve, your engineering is showing. We demand that ONLY BLUE INK Zebra G2 0.5mm are used when we convert and mark-up our prints from metric to english. Being in a machine shop, everything is written out to the thousandths and occasionally, based on tolerance, out to "tenths" (of thousandths) which we will write that fouth decimal spot in superscript and underline to draw extra attention. Funny thing is, we actually limit the use of the blue 0.5's for this purpose alone. Standard issue BLACK 0.7mm's are distributed freely... I think this keeps everyone happy enough that they keep their mitts off the BLUE BEAUTIES.

[@StevePierson123]

@@AMI_Detail and then there are those barbarians who write with a 1mm tip. Might as well be a magic marker 😅. I tried the 0.3 but it kept piercing my cheap notebook paper. Good call on the colors, got to protect those blues!

[@BrillianceAutoSpa]

Does this apply to any chemical? What if you're using a heavier soap?

[@StevePierson123]

@@BrillianceAutoSpa This is a great question. In short, yes, this works with any chemical as long as it’s similar to water when diluted. When we take a soap (thick or thin) and dilute it, the viscosity is similar to water. The cannons that draw straight from the soap bottle (like the Griots cannon) will have a different mixture rate from soap to soap. Undiluted thick soaps will not flow as quickly as thinner soaps, which completely changes the mixture rate of the cannon. If you were to do this test straight with soap, it would not work accurately. We would need to measure the density of the soap to accurately relate volume and mass.

[@BrillianceAutoSpa]

@StevePierson123 thanks for the explanation. I was thinking density of soaps in a Griots foam canon. In this case, measuring volume over weight would be better?

[@StevePierson123]

@@BrillianceAutoSpa If you have the ability to measure by volume, then you can use this same sheet. But finding the density and doing it by weight will be easier in the long run since thick soaps are tedious to work with undiluted. I had been thinking about this particular issue, it wouldn’t take much to create a separate procedure and excel sheet for the Boss cannons out there.

[@AMI_Detail]

​@@StevePierson123 The BOSS metering tips is what started my journey down the PIR rabbit hole. Crazy part about the BOSS system is that when you follow your worksheet and enter the values into your PIR spreadsheet, the mixing rate equals the PIR for that metering tip. This is what prompted me to back-figure to dilution ratios to arrive at some sort of correlation. I entered my numbers from when I measured the Aqua tip (pretending ml were grams) - 0 bucket initial, 100 foam cannon initial, 4700 bucket with water, 0 foam cannon after. The mixing rate worked out to 0.0213 - same as the 2.13% PIR that I calculated.

[@StevePierson123]

@@AMI_Detail I didn't even think of that 😅 It makes sense since there is no water dilution in the bottle. The mixture rate is basically the concentration of the bottle in the output stream. If there is no water in the bottle (soap only) then the mixture rate will be the same as the PIR.
