Pressure drop test
pressure_drop_test_kpa
Pressure drop during the flow test
Scores if within ±3% of the reference value.
Calculates available flow at a target residual pressure from static pressure, residual pressure, and measured test flow using the standard hydrant flow extrapolation exponent. The template reports pressure drops and available flow in L/s and m3/h.
with-tool: The model is given an executable Python calculator script.
Standards
One template produces many comparable benchmark tasks while keeping the scoring contract fixed.
01
The reusable contract shown on this page.
02
An archetype and site context are sampled.
03
Inputs may be hidden at harder tiers.
04
The model responds with the declared outputs.
Inputs the model receives, and the outputs it is scored on.
4 inputs
Included directly in every task prompt.
Static pressure
static_pressure_kpa
Static pressure before flow test
Residual pressure
residual_pressure_kpa
Residual pressure during flow test
Test flow
test_flow_l_s
Measured test flow
Target residual pressure
target_residual_pressure_kpa
Target residual pressure for available flow
4 outputs
pressure_drop_test_kpa
Pressure drop during the flow test
Scores if within ±3% of the reference value.
pressure_drop_target_kpa
Pressure drop from static to target residual
Scores if within ±3% of the reference value.
available_flow_l_s
Available flow at target residual pressure
Scores if within ±3% of the reference value.
available_flow_m3_h
Available flow in cubic metres per hour
Scores if within ±3% of the reference value.
Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.
For this template, difficulty scales through parameter and scenario ranges rather than hidden information.
The exact instruction and parameter contract used to generate this task, pinned to the published library source.
