snip .. I had to do snip laundry,snip

It did make me wonder if it is possible to estimate drying times for various
items based on such factors as wind speed, humidity, sunshine. snip


Theoretically, yes, there is Penman equation to calculate potential
evaporation based on those factors. Laundry, though, is more
complicated than standard Class A pan (standard equipment for
measuring evaporation), as thickness of the textiles probably affects
the effect of the windspeed. And Penman counts on unshadowed sunshine
on horisontal plane, whihc is different from laundy conditions,
especially in the UK.

In Scandinavia, there is no stigma (or very little) in drying laundry.
Sheets on lines mean "here lives a good wife who saves no trouble to
get comfortable sheets for her family". I dry stuff outdoors when it's
not pollen season, not raining, no rain forecasted and not
fingers-freezing cold. This block also has an indoors drying room with
condensating equipment, fan and ventilation. I think line-drying gives
better results and wears the textiles less than a tumble drier.

Where we lived in the UK, the lines were hidden between garage and an
overgrown hedge, so you could expect windspeed zero, sunshine zero.
Conditions "not pollen season, not raining, no rain forecasted" were
never true, and drying stuff indoors caused war with neighbours (as it
was visible from windows). I suspect laundry on the lines means "here
lives a poor family who cannot afford tumble drier" ?

ps. I live with a man who voluntarily brings the clean laundry in, and
in emergency cases does the other parts, too.
