Orifice Flow vs PrepTracker

Measurement of fluid flow in pipes and conduits using orifice plates are very common in industrial applications. This app quickly computes the flow rates for liquid and gases based on standard parameters as per the model shown. Users can pick any fluid from a list of fifteen most common fluids used in industrial applications. Therefore, this app can be a very helpful tool for practicing engineers and designers in design and analysis of flows in different applications. A case study on CO2 flow rate is shown in the screen shot. The result is consistent with other methods used by the industry in computation and difference is less than 0.1%. Fluids that are not in the list, users can create a custom fluid with property data and compute the flow rate using the model provided in this app. Custom fluid data can be saved and reloaded every time when custom fluid is selected. Fluids: Air, Steam, Water, Nitrogen, Oxygen, Hydrogen, Helium, CO2, Methane, Ethane, Chlorine, Ammonia, Argon, Hydraulic oil, HFC(R410A), Custom (user's choice). Orifice Type: App gives four different standard orifice design with recommended discharge coefficients as shown in the following screen shot. It also provides the details of the model used in the computation of flow rates for liquid and gases. This model is valid even for nozzles, venturi-flow meters for which the discharge coefficient (Cd) is unity. Measuring Parameters: Fluid inlet temperature and pressure, orifice geometry, pressure differential using standard pressure taps (ISO 5167), are the standard parameters required in the computation. Based on the orifice geometry, recommended discharge coefficient Cd is used. However, users can edit this using manufacturer’s data for more accurate results. App notes provides brief description of different orifice parameters for quick reference. Unit of Measurement: Users can choose different unit of measurement for both flow as well as pressure drop under given unit standard (SI or USCS). This can be conveniently selected while choosing the fluid from the picker list. App notes provides additional guideline with a link for complete documentation on implementation and validation of math-models used with industry examples.

Here's everything paste-ready for the fields on this page: Promotional Text: Free, private, offline. See how many days your household could last and what to stock next. Widgets, outage mode, and go-bag checklists included. Description: PrepTracker helps your household stay quietly ready for power cuts, storms, and everyday disruptions. It is free, it works fully offline, and your data stays on your phone. No account. No ads. No tracking. SEE YOUR RUNWAY Log the water, food, and supplies you already have. PrepTracker shows how many days your household could last, what runs out first, and the next thing worth adding. Targets scale to your household, including kids and pets. BE READY FOR OUTAGES The power runway estimates how long your batteries and power stations can carry the essentials. When the power goes out, Outage Mode puts food safety timers, a flashlight, and your plan on one calm screen, with a Live Activity countdown on your Lock Screen. GO-BAGS THAT BUILD THEMSELVES Start from ready-made templates for a 72-hour bag, car kit, kids' bag, pet bag, and documents pouch, then check items off as you pack. Your readiness score updates as you go. KEEP THE IMPORTANT THINGS CLOSE Store emergency contacts, medical cards, and evacuation routes. Lock sensitive notes in a vault protected by Face ID. Add widgets to your Home Screen and Lock Screen so your runway is always one glance away. PRIVATE BY DESIGN Everything lives on your device. There is no login, no cloud account, and nothing to sync. If you choose the optional weekly email digest, your device sends only a short summary you can read before it goes. CALM, NOT ALARMING PrepTracker is built for ordinary households, not bunkers. Regional starter packs suggest sensible supplies for where you live, and the app nudges you toward small, steady progress. PrepTracker offers general preparedness guidance only, not professional emergency advice. In an emergency, follow instructions from local authorities. A product of Cubed Holdings LLC.
