HydroCal 2.0 is a useful application for calculating hydraulic values. The application has been made to make it as simple as possible to use while maintaining optimal accuracy. It includes information sections that explain the calculations and formulas used to better understand the data. To complete the offer, the application also includes an electrical form section to perform simple calculations of power, voltage, current and resistance definition. This section is also accompanied by a page of brief information on the values used and the components. The application includes the following sections: - Pump with Torque, Flow, Power, - Engine with Torque, RPM, Power, - Cylinder buckling with calculation of the limit load according to the assembly, - Power of a cylinder with different data variance, - Speed of a cylinder with different data variance and flow rate definition, - Force of a cylinder with different calculation mode, - Data of a cylinder with the calculation of volume, section and delatV as well as the k-factor, - Flexible with the calculation of pressure drops in a pipe, - Connections with the calculation of a pressure drop in a given type of connection, also, table of recognition of the connections according to size and thread. - Nozzle with calculation of pressure drop as a function of diameter, - Further calculations with determination of different hydraulic-related data according to known constants, - Section on mineral hydraulic oils, explanation and graph of viscosity according to temperature. - Conversion with a conversion tool for flow, pressure, power, force, length, speed, surface, volume, viscosity and temperature data. - Electric with Power, Voltage, Intensity and Resistance. Also a resistance recognition module according to the color of the rings. All calculations are accompanied by a function to share results by email, message or any other type of platform. The calculation pages are also accompanied by a function to save the results, which can then be shared.
