Disclaimer
Last updated: August 2026
The information, engineering calculators, formulas, technical explanations, reference material, and other content provided on EngiBench.com are intended for general engineering, educational, and informational purposes only.
1. General Engineering Disclaimer
EngiBench provides calculation tools and technical content to help users perform preliminary engineering estimates, comparisons, checks, and educational calculations.
Results depend on the values entered by the user, the selected calculation method, unit conversions, assumptions, operating conditions, material or fluid properties, equipment characteristics, and the limitations of the applicable equation or model.
A mathematically correct result is not automatically a complete or approved engineering design.
2. No Professional Engineering Advice
EngiBench does not provide professional engineering services, engineering certification, design approval, code approval, equipment approval, legal advice, safety approval, or regulatory approval through the website.
Use of EngiBench does not create an engineer-client, consultant-client, contractor-client, or other professional relationship.
Projects involving safety, public infrastructure, electrical protection, pressure systems, structural integrity, hazardous processes, regulated equipment, or other high-consequence applications should be reviewed by a qualified professional using the applicable project data, codes, standards, regulations, and manufacturer information.
3. Calculator Results
Engineering calculator outputs are estimates based on the formulas and assumptions stated on the relevant calculator page. Users are responsible for confirming that the selected method is appropriate for the actual application.
Before relying on a calculator result, verify:
- all entered values and units;
- the applicable formula and calculation mode;
- fluid, material, electrical, thermal, or mechanical property data;
- operating conditions and boundary conditions;
- equipment ratings and manufacturer performance data;
- applicable codes, standards, regulations, and project requirements.
4. Accuracy of Information
EngiBench aims to provide accurate equations, unit conversions, calculation logic, engineering explanations, and reference links. However, no guarantee is made that every page, formula, reference, example, or calculator is free from errors, omissions, outdated information, or inappropriate assumptions for a specific application.
Engineering standards, regulations, manufacturer data, reference documents, and external sources may change over time. Where accuracy or compliance is important, users should verify information against the current authoritative source.
5. Reference Values and Example Data
Example values, default inputs, reference efficiencies, fluid properties, roughness values, atmospheric conditions, safety margins, and other example parameters are provided for convenience or illustration unless specifically stated otherwise.
They should not be treated as universal design values. Actual values can vary with temperature, pressure, altitude, equipment type, material condition, manufacturing tolerances, operating load, system configuration, and other factors.
6. Equipment Selection and Sizing
Unless a calculator explicitly states that it performs a specific sizing method, EngiBench results should not be interpreted as final equipment selection.
Final selection of pumps, motors, boilers, valves, piping, ducts, electrical conductors, breakers, vessels, heat-transfer equipment, or other components may require manufacturer curves, certified data, detailed system analysis, design margins, code requirements, environmental conditions, and professional engineering review.
7. Safety-Critical Applications
Do not rely on EngiBench as the sole basis for a safety-critical decision. Calculators on this website do not replace hazard analysis, relief-system design, protection coordination, structural verification, pressure-vessel design, electrical code review, process safety analysis, or other specialized safety procedures.
Always use appropriate professional judgment, verified data, applicable standards, manufacturer documentation, and qualified review for high-risk applications.
8. Third-Party References and External Links
EngiBench may link to government agencies, standards organizations, manufacturers, educational resources, engineering references, technical publications, and other third-party websites.
External links are provided for reference and convenience. EngiBench does not control third-party websites and does not guarantee their continued availability, accuracy, completeness, security, or future content.
A citation or external link does not imply endorsement, sponsorship, partnership, or approval unless explicitly stated.
9. Regulatory and Standards Information
Any discussion of codes, regulations, standards, efficiency requirements, recommended practices, or compliance topics is provided for general reference only.
Requirements can depend on jurisdiction, equipment classification, installation date, manufacturing date, application, rated capacity, design category, and other project-specific factors. Users are responsible for consulting the current official text and determining which requirements apply.
10. No Warranty
EngiBench and its content are provided on an “as is” and “as available” basis. To the extent permitted by applicable law, EngiBench disclaims warranties of accuracy, completeness, reliability, suitability, merchantability, fitness for a particular purpose, non-infringement, and uninterrupted availability.
11. Limitation of Liability
To the extent permitted by applicable law, EngiBench and its operators will not be liable for any direct, indirect, incidental, consequential, special, or other losses or damages resulting from the use of, inability to use, or reliance on the website, calculators, formulas, technical content, reference values, or external links.
This includes losses associated with design decisions, equipment selection, construction, operation, maintenance, business interruption, project delay, property damage, equipment damage, lost data, lost profits, or other consequences arising from reliance on website information without appropriate independent verification.
12. User Responsibility
By using EngiBench, you accept responsibility for reviewing the suitability of the calculation method and for independently verifying results before applying them to an actual engineering system or project.
Where required, obtain review or approval from a qualified engineer, licensed professional, authority having jurisdiction, equipment manufacturer, or other appropriate technical specialist.
13. Changes to This Disclaimer
EngiBench may update this Disclaimer as website features, calculators, reference sources, or legal requirements change. The current version will be published on this page with an updated date.
14. Contact
