✦ Synopsis

This investigation seeks to identify the effects of partial vacuums on the steady-state drying rate of cotton plates. Five pressure levels between atmospheric pressure and 33.6 kPa (20" Hg vacuum) were tested in an aluminum vacuum chamber. Improvements in steady state drying rates on the order of 62% were obserxd at the lowest pressure level. The hoped-for design points were not discovered. Both theoretical and experimental values of the mass transfer rate are developed.
