01 / 10 · Flow & energy

Before you buy a bigger pump.

A pump and its piping form one system. The useful operating point sits where the pump curve meets the system curve.

The question to carry forward

Which part of the system resistance should change to deliver the required flow?

Explore pump & system performance →
Read the visual description

A ResEt AI conceptual pump-system animation compares pump and system curves at their operating point. Flow markers pass through a pump, piping and fittings. Changing system resistance shifts the system curve and the available operating point. The graphic is a conceptual comparison, not simulated results.

02 / 10 · Chemistry & experiments

Best yield? Or best question?

The next experiment can be valuable because it separates competing explanations, even when it is not the highest-yielding condition.

The question to carry forward

Would the predicted difference be large enough to distinguish from measurement noise and model uncertainty?

Explore experiment design →
Read the visual description

A branching diagram compares two experimental choices. Repeating a favourite condition leaves the predicted response ranges of hypotheses A and B close together. A discriminating test separates their ranges. All predictions are conceptual, not measured results.

03 / 10 · Reactions & heat

A faster reaction. A cooling question.

Compare heat generation and heat removal across the whole trajectory. A conversion target alone cannot reveal a cooling constraint.

The question to carry forward

When does heat generation outpace removal, and what evidence is needed to assess the thermal behaviour?

Explore reaction & cooling →
Read the visual description

A conceptual reactor energy diagram shows heat-generation and heat-removal arrows. As the generation rate rises above removal, the thermal-energy indicator rises. A time plot tracks the two rates. This closed-system illustration is not a safety assessment.

04 / 10 · Models & evidence

A perfect fit. An open question.

Two models can fit the same observations and disagree in an untested region. A clean fit is not proof of the proposed mechanism.

The question to carry forward

Which feasible new condition would most clearly challenge the explanation?

Explore experiment design →
Read the visual description

Two conceptual model curves overlap across an observed region, then diverge under new conditions. Uncertainty bands widen beyond the observations, and a dashed line identifies a potential discriminating check. No fitted or measured results are shown.

05 / 10 · Fermentation & scale-up

One probe. A moving cell.

A fixed probe and a moving cell experience different parts of a vessel. Mixing, oxygen transfer and uptake shape the cell’s journey.

The question to carry forward

Where would the next measurement help distinguish a local oxygen constraint from another cause?

Explore fermentation scale-up →
Read the visual description

A lime cell moves around a conceptual bioreactor, crossing an oxygen-rich upper zone and oxygen-poor lower zone. A fixed probe remains in the upper zone. The animation contrasts the probe’s local reading with the moving cell’s changing exposure. No oxygen measurements are shown.

06 / 10 · Heat & design

More cooling flow. Same bottleneck?

Heat crosses several resistances in series. Improving one fluid film can have a limited benefit when another resistance dominates.

The question to carry forward

Is the controlling resistance in the fluid films, the wall or a fouling layer?

Explore thermal design →
Read the visual description

Heat-flow markers cross four blocks: hot-side film, wall, fouling layer and cold-side film. A conceptual resistance bar shortens on the coolant side as cooling flow increases, while the larger fouling contribution remains. The example illustrates a possible dominant resistance, not measured exchanger performance.

07 / 10 · Thermodynamics

Heat added. Temperature flat.

For a pure substance in equilibrium at fixed pressure, heat can increase vapour fraction during a liquid–vapour transition without raising saturation temperature.

The question to carry forward

Does the property model represent the pressure, material and phases actually present?

Explore phase change & duty →
Read the visual description

A conceptual temperature-versus-specific-enthalpy path rises, plateaus during liquid–vapor phase change, then rises again. Equal-mass tiles change from liquid to vapor while the curve is flat. The graphic states pure substance, equilibrium and fixed pressure below the critical pressure.

08 / 10 · Engineering & energy

A little more air. A steeper power bill.

Under the fan-affinity assumptions, flow scales with speed and shaft power with speed cubed. Check the actual system before applying those ratios.

The question to carry forward

What duty is required, and do efficiency, density and system resistance support the comparison?

Explore the Draught Fan Lab →
Read the visual description

Forest-green ResEt AI animation: a fan rotates beside airflow, pressure and shaft-power bars. As an idealized speed ratio rises from 1.00 to 1.10, ratios rise to 1.10, 1.21 and 1.33 respectively. The same-geometry, air-density, similar-operation and constant-efficiency assumptions are labeled. No measured performance is shown.

09 / 10 · Measurement & evidence

What happened between samples?

A smooth line through sparse samples can miss a fast event. Denser acquisition is new evidence, not detail recovered from the original record.

The question to carry forward

Do the process timescales, sensor response and acquisition bandwidth resolve the event that matters?

Explore connected engineering models →
Read the visual description

Two stacked conceptual sampling timelines. Sparse sample dots miss a narrow transient, which appears between them in an illustrative signal. A separate, denser acquisition reveals the pulse with additional sample dots. The graphic states that a line between points is not a new measurement.

10 / 10 · CFD & evidence

A finer mesh. A better answer?

Grid convergence addresses numerical error. Validation is a separate comparison with physical measurements for the intended use.

The question to carry forward

Have the numerics and the physical model both been checked for the decision at hand?

Explore the CFD lab & evidence →
Read the visual description

Two-part ResEt AI animation distinguishes verification from validation. Three progressively finer schematic meshes accompany a stabilizing quantity-of-interest trend. Separately, a simulation marker is compared with an experimental marker and uncertainty bar. All marks are labeled conceptual, not simulation or test results.
