CavitcityScoutApp is a handy pump toolkit that keeps your system safe and efficient by putting the key checks in one place. It quickly works out Total Dynamic Head, covering static, friction, minor, and velocity head. It finds NPSH Available from real site conditions and gives a clear Cavitation Risk check by comparing NPSHa to NPSHr with a safety margin. It estimates brake horsepower and motor kW from flow, head, efficiency, and service factor. A simple field test tool estimates pump efficiency from measured flow, head, and kW. It shows how pumps act in series or parallel with combined head/flow curves to pick the right duty point. It helps choose pipe size to cap head loss per 100 m using Darcy–Weisbach or Hazen–Williams for straight runs and K-values for fittings. It also checks suction lift limits based on temperature and altitude so you can spot problems before they start.
