HOW THIS VERIFICATION WORKS

  1. Step 1: Required Relief Orifice Area for Liquid Service — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  2. Step 2: Standard Orifice Selection and Actual Capacity — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  3. Step 3: Built-Up Backpressure Verification — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.

This tool coordinates 1 validation step and 2 calculation steps. The overall engineering decision uses ALL_REQUIRED_VALIDATION_PASS aggregation: only validation steps contribute to the pass/fail outcome; calculation steps produce data only.

METHODS & EQUATIONS

All formulas are resolved from canonical runtime definitions and executed deterministically by the client-side engine.

Step 1: Required Relief Orifice Area for Liquid Service

FormulaA_required = Q_relief / (K_d * K_w * K_v) * sqrt(G / (2 * 9.81 * (P_set - P_back)))

Step 2: Standard Orifice Selection and Actual Capacity

FormulaA_selected = A_required * 1.1; C_actual = K_d * A_selected * K_w * K_v * sqrt(2 * 9.81 * (P_set - P_back) / G)

Step 3: Built-Up Backpressure Verification

FormulaP_built_up = P_back + delta_P_acc; P_back_ratio = P_built_up / P_set; P_back_pass = P_back_ratio <= 0.10

UNDERSTANDING THE RESULTS

PASS
A proven validation criterion passed. The engineering input satisfies the deterministic threshold.
FAIL
A proven validation criterion failed. The engineering input does not satisfy the deterministic threshold.
CALCULATED
A deterministic calculation completed, but no acceptance criterion exists for this step. CALCULATED does NOT mean PASS.
RESULT NOT VALID
Runtime executed but engineering validity requirements were not met.
INCOMPLETE
Required inputs or workflow steps are incomplete.

The overall decision reflects only validation steps. Calculation steps produce numerical results without pass/fail claims.

WHEN TO USE THIS TOOL

  • When deterministic Reverse Osmosis System engineering verification is needed for project-specific conditions.
  • For calculation of Required Relief Orifice Area for Liquid Service (Step 1).
  • For calculation of Standard Orifice Selection and Actual Capacity (Step 2).
  • For validation of Built-Up Backpressure Verification (Step 3).
  • For deterministic pre-checks before formal engineering review or submission.

When NOT to use this tool: This tool does not replace laboratory testing, formal engineering analysis by a licensed professional, or code-compliance certification. It performs deterministic threshold comparison and calculation only.

ENGINEERING FAQ

What does this verification tool check?

This tool performs 3 deterministic engineering steps: (1) Required Relief Orifice Area for Liquid Service, (2) Standard Orifice Selection and Actual Capacity, (3) Built-Up Backpressure Verification.

What does a PASS result mean?

A PASS result means the validation step's deterministic threshold comparison was satisfied. It does not constitute laboratory certification or code compliance.

What does a CALCULATED result mean?

A CALCULATED result means the deterministic calculation completed, but no acceptance criterion is applied to this step. CALCULATED does NOT mean PASS.
