Small fluid mechanics helpers for RustUse.

use-fluid = "0.0.1"

Foundation

use-fluid provides small fluid mechanics helpers for buoyancy, hydrostatic pressure, flow rate, continuity, Bernoulli-style relations, viscosity, Reynolds number, and simple drag calculations.

Inputs are expected to be SI-style numeric values:

• kilograms per cubic meter for density
• cubic meters for volume
• meters per second squared for acceleration
• newtons for force
• pascals for pressure
• meters for depth, height, and characteristic length
• square meters for area
• cubic meters per second for volumetric flow rate
• kilograms per second for mass flow rate
• pascal-seconds for dynamic viscosity
• square meters per second for kinematic viscosity

This crate does not define a full unit system.

More general units and constants belong in the top-level use-units and use-constants sets.

Material databases belong in top-level use-materials.

This crate is not a CFD solver.

Example

use use_fluid::{Fluid, PipeFlow, dynamic_pressure};

let water = Fluid::with_dynamic_viscosity(1000.0, 0.001).unwrap();
let flow = PipeFlow::new(2.0, 3.0).unwrap();

assert_eq!(flow.volumetric_flow_rate(), Some(6.0));
assert_eq!(flow.mass_flow_rate(water.density), Some(6000.0));
assert_eq!(dynamic_pressure(water.density, 3.0), Some(4500.0));

When to use directly

Choose use-fluid when you only need reusable fluid mechanics formulas without a full units or simulation stack.

Scope

• APIs stay f64-first and do not define a full unit system.
• Simple scalar helpers only; CFD, turbulence modeling, and material datasets are out of scope.
• Broader units, constants, and materials belong in the top-level RustUse sets.

Status

use-fluid is a pre-1.0 crate with a deliberately small API. Small fluid mechanics helpers.
