Today vs HydroCalc Plus

"Today" is a simple daily planner that allows you to quickly plan your day, starting from a clean page. Tasks don't pile up: everything incomplete, stale, and postponed is out of your sight until you decide to review it. So instead of being upset about unfinished plans, you can stay in a good mood for the day ahead and focus on what's important today. Features: - Adding and editing tasks is really quick and convenient - Postpone a task for later in a single tap - Optional "Daily note" for the day – to focus on one goal, or just something to remember - Events from iOS Calendar are added automatically - Indicate task priorities with bold, italic or underlined text - Copy/paste tasks between days and from other apps

The COMPLETE version of HydroCalc, with what the free app doesn't have: the FITTINGS SELECTOR. Pick elbows, valves, tees and reducers piece by piece and the app computes minor losses for you — in the calculator, the inverse calculator and the system curve. No K-value tables, no transcription errors. ALL INCLUDED: pump power, system curve, pipe database and Darcy-Weisbach with real fluids come with the app. One purchase, no in-app purchases. Professional hydraulic engineering tool for calculating pressure losses in piping systems. Essential for engineers, plumbers, and contractors designing water distribution networks. Key Features: Calculate friction head losses using industry-standard Hazen-Williams equation Support for both US (ft, gpm, psi) and SI (m, lps, bar) units Extensive pipe material library with pre-defined roughness coefficients (C-factors) Complete fittings and valves database including elbows, tees, valves, contractions, and expansions Inverse calculations to determine optimal pipe diameter, flow rate, or length for target head loss Real-time results showing velocity, friction loss, minor losses, and total system head loss What Sets Plus Apart: Unlike basic calculators, HydroCalc Plus accounts for both major losses (pipe friction) and minor losses (fittings and valves). The app includes a comprehensive database of K-factors for various components, allowing accurate total system pressure loss calculations. Perfect For: Water supply system design Irrigation network planning HVAC piping calculations Fire protection systems Industrial fluid transport Educational purposes in hydraulic engineering Technical Capabilities: The app considers all critical factors affecting pressure loss: flow velocity, pipe diameter, internal roughness, pipe length, and fitting configurations. Materials include PVC, polyethylene, steel, cast iron, concrete, and more with accurate C-factors ranging from 120-150. Inverse Calculation Mode: Unique feature allowing backward calculations - determine required pipe size for allowable head loss, maximum flow capacity, or optimal pipe length for your system constraints. Simple, intuitive interface with instant results. No internet connection required. Professional-grade calculations in your pocket. Note: the advanced modules are available in English and Spanish.
