ktsu.PhysicalQuantity

PhysicalQuantity is a .NET library that provides a robust framework for working with physical quantities, supporting a wide range of units and conversions.

Features

• Comprehensive Unit Support: Supports a wide range of physical quantities including length, mass, time, energy, and more.
• Accurate Conversions: Provides accurate unit conversions for each quantity.
• Significant Numbers: Uses the SignificantNumber library to maintain precision in calculations.
• Extensibility: Easily extendable to support custom units and quantities.

Installation

To install PhysicalQuantity, run the following command in your .NET project:

dotnet add package ktsu.PhysicalQuantity

Usage

Basic Example

using ktsu.PhysicalQuantity.Length;
using ktsu.SignificantNumber;

Length lengthInMeters = 100.Meters();
float lengthInKilometers = lengthInMeters.Kilometers<float>();

Console.WriteLine($"{lengthInMeters} is equal to {lengthInKilometers} kilometers");

Supported Quantities

• Acceleration
• AmountOfSubstance
• Angle
• AngularAcceleration
• AngularVelocity
• Area
• Density
• ElectricCurrent
• ElectricPotential
• Energy
• Force
• Illuminance
• Jerk
• Length
• LuminousFlux
• LuminousIntensity
• Mass
• Power
• Pressure
• Resistance
• Temperature
• Time
• Torque
• Velocity
• Volume

Example Conversion

using ktsu.PhysicalQuantity.Mass;
using ktsu.SignificantNumber;

Mass massInKilograms = 70.Kilograms();
float massInPounds = massInKilograms.Pounds<float>();

Console.WriteLine($"{massInKilograms} is equal to {massInPounds} pounds");

Integrating and Deriving Quantities

The PhysicalQuantity library supports operations for integrating and deriving physical quantities, making it easier to work with quantities that result from these operations.

Deriving Quantities

To derive a quantity, you can use the appropriate operators provided by the IIntegrationOperators interface. For example, deriving velocity from distance and time:

using ktsu.PhysicalQuantity.Length;
using ktsu.PhysicalQuantity.Time;
using ktsu.PhysicalQuantity.Velocity;
using ktsu.SignificantNumber;

Length distance = 100.Meters();
Time time = 10.Seconds();
Velocity velocity = distance / time;

Console.WriteLine($"Velocity: {velocity}"); // Output: Velocity: 10 m/s

Integrating Quantities

To integrate quantities, you can use the appropriate operators. For example, integrating acceleration over time to get velocity:

using ktsu.PhysicalQuantity.Acceleration;
using ktsu.PhysicalQuantity.Time;
using ktsu.PhysicalQuantity.Velocity;
using ktsu.SignificantNumber;

Acceleration acceleration = 9.8.MetersPerSecondSquared();
Time time = 5.Seconds();
Velocity velocity = acceleration * time;

Console.WriteLine($"Velocity: {velocity}"); // Output: Velocity: 49 m/s

Example

Here's a more comprehensive example that demonstrates both integration and derivation:

using ktsu.PhysicalQuantity.Acceleration;
using ktsu.PhysicalQuantity.Length;
using ktsu.PhysicalQuantity.Time;
using ktsu.PhysicalQuantity.Velocity;
using ktsu.SignificantNumber;

Length initialDistance = 0.Meters();
Velocity initialVelocity = 0.MetersPerSecond();
Acceleration acceleration = 9.8.MetersPerSecondSquared();
Time time = 10.Seconds();

// Calculate final velocity: v = u + at
Velocity finalVelocity = initialVelocity + acceleration * time;

// Calculate distance traveled: s = ut + 0.5 * a * t^2
Length distance = initialVelocity * time + 0.5 * acceleration * time * time;

Console.WriteLine($"Final Velocity: {finalVelocity}"); // Output: Final Velocity: 98 m/s
Console.WriteLine($"Distance Traveled: {distance}");   // Output: Distance Traveled: 490 m

By using these integration and derivation methods, you can handle a wide range of physical calculations with ease.
