Description:
 def num_orifices(FlowPlant, RatioVCOrifice, HeadLossOrifice, DiamOrifice):
 """Return the number of orifices."""

    #Inputs do not need to be checked here because they are checked by
    #functions this function calls.
    return np.ceil(area_orifice(HeadLossOrifice, RatioVCOrifice,
                                 FlowPlant).magnitude
                    / area_circle(DiamOrifice).magnitude)
