A transdermal delivery system was designed to release a drug through a rate-controlling membrane. The drug concentration in the reservoir was saturated and kept at 5 mcg/mL. The membrane/reservoir partition coefficient is 100, and drug diffusion coefficient in membrane is 5 x 10^-6 cm^2/sec. The membrane thinness is 1 mm, and its cross-sectional area is 10 cm^2. (Assume sink condition without lag time.). calculate the rate of diffusion(mcg/s):
