## Description

HydroCalc is a powerful yet easy-to-use mobile calculator designed for engineers, technicians, and students in the fields of hydraulic design, irrigation, water treatment, plumbing, and solar pumping systems.<br><br>With HydroCalc, you can quickly calculate head loss in pipes using the Hazen-Williams equation and account for both pipe friction and minor losses from fittings.<br><br>💧 Features:<br>• Calculate total head loss from pipe length, flow, diameter, and roughness<br>• Use SI (metric) or US units easily<br>• Add minor loss coefficient (K) to include fittings and valves<br>• See flow velocity, friction loss, and total head loss instantly<br>• Inverse calculations: calculate required pipe diameter, max flow, or max pipe length from a head loss limit<br><br>🔄 Inverse Calculations:<br>• Calculate the required pipe diameter for a given head loss<br>• Find the maximum flow rate allowed for a pipe<br>• Determine the maximum pipe length to stay under a head loss constraint<br><br>Whether you&#39;re sizing a pipeline or checking a design in the field, HydroCalc puts hydraulic calculations in your pocket.<br><br>Perfect for professionals and students working with water systems.
