Hi, Jack,

When Paul Newman had raindrops falling on his head in Butch Cassidy
and the Sundance Kid (sung by BJ Thomas - a far superior version to
Sacha's imho), he was riding around on a bicycle. How would that
affect the amount falling on his head? He was riding in a circle at
just above walking pace, had a brimmed cowboy hat on and had Katharine
Rodd on his knee. It was also in 1969, before AGW(;0)

Raindrops fell on my head last night when I was getting the coal in
btw
15.5mm at 09Z this morning (exactly the same as Saturday 09Z reading)

There was a New Scientist article once about whether running through the
rain rather than walking made any difference. I think the conclusion was
that it didnt make that much difference cos you run into raindrops that
would have otherwise missed you.

But googling brings up this article:
http://www.abc.net.au/science/k2/moments/gmis9749.htm

which suggests that if its raining heavily with the wind blowing towards
you you would end up 44% less wet. Which if my previous answer were
right and he were to remove his hat you could I suppose guess it would
be just under 10g of rain on his head.

Now having worked out that my disney cowboy hat has an area of approx:
0.125m2 If he cycles for 10min at 5mm rainfall rate and assuming 44%
less wet then I think he will have had 46g land on his hat.

Sarah - perhaps I should get on with some work now!
