Plumbing Uv Disinfection Dose Calculator
Integrate actual matched UV intensity trajectory by trapezoids to observed fluence, no uniform field/residence assumption, germicidal wavelength inference or disinfection certification.
Description
UV fluence integrates irradiance over exposure time.
UV fluence integrates irradiance over exposure time. Discrete measurements support a trapezoidal estimate when time is strictly ordered.1
The returned values include Observed integrated uv fluence mj cm2. The How section below explains the calculation, input rules and interpretation.
When to use Plumbing Uv Disinfection Dose Calculator
Use Plumbing Uv Disinfection Dose Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No wavelength, reactor geometry, microbial reduction or certified disinfection performance is inferred.
Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
How to use Plumbing Uv Disinfection Dose Calculator and understand its results
- Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
- Enter observedUvExposureTimesSeconds, observedMatchedUvIntensityMwCm2 using the field table and calculation rules, then run the tool.
- Read observedIntegratedUvFluenceMjCm2. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedUvExposureTimesSeconds | Observed uv exposure times seconds | list of number | Required |
| observedMatchedUvIntensityMwCm2 | Observed matched uv intensity mw cm2 | list of number | Required |
Enter aligned nonempty nonnegative seconds and irradiance values, with at least two strictly increasing times. Return integrated dose in mJ/cm².
dose=sum((I_i+I_next)/2×(t_next−t_i)) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedIntegratedUvFluenceMjCm2 | Observed integrated uv fluence mj cm2 | number |

}Limitations and assumptions
No wavelength, reactor geometry, microbial reduction or certified disinfection performance is inferred.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Use Plumbing Chlorine Contact Time Calculator: Chlorine CT multiplies measured residual concentration by effective contact time. A baffling fraction adjusts nominal volume/flow residence time. For a complementary task, use Plumbing Interceptor Oil Separation Efficiency Calculator: Oil-removal efficiency compares paired inlet and outlet inventories. Matched water volumes provide mass weights for the pooled result.
