I will report the analyses of winds in a sample of starburst galaxies in the COS Legacy Archive Spectroscopic SurveY (CLASSY). The high quality and broad spectral coverage of CLASSY data enable us to measure the outflow's mean velocity, velocity width, column density, and outflow rates of metals, mass, momentum, and kinetic energy. I then study various scaling relationships by comparing these outflow properties to galaxy properties, e.g., star-formation rate, galaxy mass, and circular velocity. I also present a novel method to measure the gas electron density in outflows, which in turn yields estimates of outflow cloud properties (e.g., density, volume filling-factor, and sizes/masses). The derived density correlates well with the galaxy's star-formation rate per unit area. Based on comparisons to theoretical models of multi-phase outflows, nearly all of the outflows have cloud sizes large enough for the clouds to survive their interaction with the hot wind fluid. Most of these measurements are novel for galactic winds detected in absorption lines and, thus, will provide essential constraints for future models of galactic winds.
