Struct Fluid 

pub struct Fluid {
    pub density: f64,
    pub dynamic_viscosity: Option<f64>,
}

A simple fluid model with density and optional dynamic viscosity.

Fields

density: f64

dynamic_viscosity: Option<f64>

Implementations

impl Fluid

pub fn new(density: f64) -> Option<Fluid>

Creates a fluid from density when the density is non-negative and finite.

pub fn with_dynamic_viscosity( density: f64, dynamic_viscosity: f64, ) -> Option<Fluid>

Creates a fluid from density and dynamic viscosity when both values are non-negative and finite.

pub fn buoyant_force( &self, displaced_volume: f64, gravitational_acceleration: f64, ) -> Option<f64>

Computes buoyant force for a displaced volume in this fluid.

Examples

use use_fluid::Fluid;

let water = Fluid::new(1000.0).unwrap();
let force = water.buoyant_force(0.01, 9.80665).unwrap();

assert!((force - 98.0665).abs() < 1.0e-10);

pub fn hydrostatic_pressure( &self, gravitational_acceleration: f64, depth: f64, ) -> Option<f64>

Computes hydrostatic pressure at a depth in this fluid.

pub fn dynamic_pressure(&self, velocity: f64) -> Option<f64>

Computes dynamic pressure for this fluid at a given velocity.

pub fn reynolds_number( &self, velocity: f64, characteristic_length: f64, ) -> Option<f64>

Computes Reynolds number for this fluid when dynamic viscosity is available.

Trait Implementations

impl Clone for Fluid

fn clone(&self) -> Fluid

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Fluid

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Fluid

fn eq(&self, other: &Fluid) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
