Engenharia e Cia: Calculadora

Technical flow and diameter calculator for engineering.

Engineering and Co.: Calculator is a technical application aimed at engineers, technologists, and professionals working with fluid flow, hydraulic sizing, and industrial plant analysis.
The application was developed with a focus on practical applicability, allowing essential calculations to be performed quickly, reliably, and in a standardized way, without depending on spreadsheets or complex software.
The calculations follow established engineering concepts and are presented with clear units, organized results, and basic validations to avoid inconsistencies.
Calculations available in the application:
• Average flow rate and minimum and maximum diameters
Calculation of average flow rate from volume and filling or emptying time, with estimation of compatible diameters for the application.
• Average flow velocity
Determination of average velocity from flow rate and internal pipe diameter, assisting in verifying recommended limits.
• Pressure Unit Conversion
Conversion between various units commonly used in engineering, such as Pa, kPa, MPa, bar, mca, psi, mmHg, among others.
• Distributed Head Loss
Calculation of head loss along the pipeline considering length, diameter, flow rate, fluid properties, flow regime, and material roughness.
• Localized Head Loss
Calculation of losses associated with fittings such as elbows, bends, valves, inlets, and outlets, with the possibility of obtaining the loss in meters of fluid column and pressure.
• Available NPSH
Calculation of available NPSH from suction conditions, absolute pressure, vapor pressure, head losses, and geometric height, assisting in cavitation analysis.
• Hydraulic Power and Shaft Power
Determination of hydraulic power of the flow and shaft power, with optional efficiency, including results in W, kW, and HP.
Application Features:
- Simple and objective interface
- Results presented clearly
- Support for the Brazilian decimal separation standard
- Widely used technical units
- Developed for technical and educational use
The application does not replace executive projects, but it functions as a reliable support tool for studies, quick checks, preliminary analyses, and field use.
Suitable for professionals in the fields of mechanical, civil, chemical, sanitation, production engineering, and related areas.
