import fluids as normal_fluids
from fluids.numerics import FakePackage
from fluids.numerics import numpy as np

"""Basic module which wraps all fluids functions with numpy's vectorize.
All other object - dicts, classes, etc - are not wrapped. Supports star
imports; so the same objects exported when importing from the main library
will be imported from here.

>>> from fluids.vectorized import *

Inputs do not need to be numpy arrays; they can be any iterable:

>>> fluids.vectorized.friction_factor(Re=[100, 1000, 10000], eD=0)
array([ 0.64      ,  0.064     ,  0.03088295])

Note that because this needs to import fluids itself, fluids.vectorized
needs to be imported separately; the following will cause an error:

>>> import fluids
>>> fluids.vectorized # Won't work, has not been imported yet

The correct syntax is as follows:

>>> import fluids.vectorized # Necessary
>>> from fluids.vectorized import * # May be used without first importing fluids


This module is lightweight! It takes approximately 3 ms to load, and increases
ram usage by only 250 KB.
