# property-utils
*Utilities for programming that involves physical properties*
## What is property-utils?
property-utils is a python library that aims at making programming with physical properties easier. It was created to be used by scientists and engineers with little programming experience.
***What is provided by property-utils?***
### Unit arithmetics
You can divide and multiply units to create new units. For example you can create velocity units by dividing length units with time units.
### Unit conversions
You can easily convert a property from one unit to another by calling a method.
### Property arithmetics
You can add, subtract, divide and multiply properties to create new properties. For example, you can create a density property by dividing a mass property with a volume property.
## Installation
```
pip install property-utils
```
## Quick usage
A simple example:
```py
import math
from property_utils.properties import p
from property_utils.units import (
BTU,
FOOT,
RANKINE,
HOUR,
CENTI_METER,
METER,
KELVIN,
KILO_WATT,
)
tube_radius = p(12, CENTI_METER)
tube_length = p(2.3, METER)
heat_exchange_area = 2 * math.pi * tube_length * tube_radius
heat_transfer_coeff = p(150, BTU / RANKINE / FOOT**2 / HOUR)
cold_in = p(273, KELVIN)
cold_out = p(300, KELVIN)
hot_in = p(520, KELVIN)
hot_out = p(472, KELVIN)
diff_in = hot_in - cold_in
diff_out = hot_out - cold_out
temperature_diff = (diff_in - diff_out) / math.log((diff_in / diff_out).value)
print("Heat transfer coefficient =", heat_transfer_coeff)
print("Heat exchange area =", heat_exchange_area)
print("Temperature difference =", temperature_diff)
heat_duty = heat_transfer_coeff * heat_exchange_area * temperature_diff
print("\nHeat duty =", heat_duty)
print(" =", heat_duty.to_si())
print(" =", heat_duty.to_unit(KILO_WATT))
```
Result:
```
Heat transfer coefficient = 150 Btu / (ft^2) / hr / °R
Heat exchange area = 1.7341591447815656 (m^2)
Logarithmic mean temperature difference = 207.24308513672648 K
Heat duty = 1044588.4611345044 Btu / hr
= 306122.45180469507 J / s
= 306.12245180469506 kW
