Drying clothes
« on: October 29, 2008, 05:05:29 PM »
A batch of wet clothes in a clothes dryer contains 0.983 kg of water. Assuming the air leaves the dryer saturated with water vapour at 48 C and 738 torr total pressure, calculate the volume of dry air at 24 C an 738 torr require to ry the clothes. the vapour pressure of water at 48 C is 83.7 torr.

I cannot understand what I have to do to get started with this. Heelp!

Why isn't anybody replying to my questions? Have I missed out something?

What is mass of water in 1L of the entering air?

What is mass of water in 1L of the leaving air?

What's a difference?

Can you do the calculations yourself, to answer Borek:'s questions?  You've mentioned in another thread that you're new to the forum's rules, so I'll be more explicit for you -- we don't give answers out here, we instead, try to give you a hint, a nudge, in the right direction.  So you'll be able to solve any problem, not just this one, and you'll be better off.  Borek:'s suggestion is, in fact, "how you get started."  Once started, you'll have more work to do, but at least you'll understand.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
