Re: [GBlist] residual laundry moisture (numbers again)



Lstiburek & Carmody in the Moisture Control Handbook (citing information from Bill Angel and W. Olsen from the U. of Minnesota) use 4.68 to 6.18 pints/load released from unvented electric drying.  I'm assuming it would also be in this range for air-drying.  I imagine this is affected not only by the washing machine, but by the clothing.  My jeans hold a lot more water than my synthetic athletic clothes.
 
If it's for your own washing machine, couldn't you just wash several loads, getting before and after weights to determine how much water is left?  You could do this with clean clothes to minimize the amount of dirt weighed in the before measurement.
 
I remember reading another source with this info, but I can't seem to locate it among my reference material. 
 
Hope this helps.

Subject: [GBlist] residual laundry moisture (numbers again)

I need some clarification.  I'm trying to determine how much moisture is left in a load of laundry after washing (in gallons).  Machines are rated by residual moisture efficiency but I'm unclear what this relates to. For eg. a machine taking 25 gallons per load with a 50% residual moisture efficiency - does this mean 12.5 gallons of water left in the load after spinning - seems unlikely
 
The reason I'm asking this is I'm trying to determine the indoor drying requirements for a load of laundry - how much moisture has to be deal with?
 
please and thank you
