Tweaking taps for a constantly warm shower
IS IT possible to have a shower of constant warmth when you're sharing a hot-water supply?
Christina Matzke at the University of Bonn in Germany and Damien Challet of the Institute for Scientific Interchange in Turin, Italy, used a mathematical model to show that shower temperature becomes increasingly sensitive to small changes in hot-water flow as the number of users increases. Thus in a youth hostel, for example, the showers often fluctuate between scalding hot and ice cold during heavy use.
The temperature can stabilise, however, if bathers adopt a range of strategies for adjusting the shower taps - for example, if some fiddle with the hot tap while others tweak the cold. But that comes at a price: what hot water there is then gets distributed evenly, so everyone's shower becomes colder than they might like.

You'll never notice the hot water necessity when you are in the Philippines because it's always hot so the cold shower comes as a blessing. But nevertheless, when I went to Harbin, I crave for the warm water. I only found out that the hotel I'm staying in turns on the Hot water supply after 7 in the morning when I got up early to take a shower to avoid the breakfast rush. Silly me, stood there in the cold shower braving the cold water in the cold bathroom. hehehe
actually, i could relate somewhat. JG's showers don't have hot water for some time now (prolly they didn't bother since we're leaving the building soon anyways). so whenever i use the showers here, i have to endure the really cold water.
hehehe... When are you guys leaving JG? I will miss that building. Spent like 4 years or more there.
early march. ako din, halos 4 years din akong nag-stay sa building na to.
hahaha oo nga. we're all veterans there. ehehe... Were you able to stay at all 5 floors? Ako 30th lng hindi ko na stay.
nope, sa 32nd at 33rd lang ako napunta.
