Blueprint of Water

Blueprint of Water puts the working numbers of industrial water treatment on your phone. Seven field calculators, built for the technician standing at the equipment. Cooling Tower: evaporation, cycles, blowdown, and makeup from the readings on the tower. Boiler: feedwater, steam, blowdown, and makeup for the steam plant. Softener: capacity, run length, salt, and efficiency. Langelier Saturation Index: scale or corrosion tendency from the water chemistry. Closed Loop: glycol target, nitrite residual, and freeze point. System Volume: the PTSA tracer method, from dose and reading to true volume. Pipe Flow: Hazen-Williams solved for the capacity a line can deliver. Everything runs on the phone. No account, no sign in, no network, and no data collection. Open it in a mechanical room with no signal and the numbers are the same ones you get on the site. Results update as you type, and the math behind each result is one tap away, so you can check the work. Name the job site, save the reading to it, and share a PDF report that carries the site name and a link that reopens the same reading in the app on someone else's phone. Blueprint of Water is the companion to the book and website of the same name at blueprintofwater.com, written for the people who keep industrial water systems running.
