Dry air at 1 atm flows at 9 m/s across the surface of a 10-inch-long surface that is covered with a thin film of water. if the air and water are at 25 c and the diffusivity of water in air is 0.25 cm2/s, estimate the water flux in kmol/s*m2 for the evaporation of water at the middle of the surface, assuming laminar boundary-layer flow. air at 25c, viscosity 1.8 x 10-5 kg/m*s. vapor pressure of water 0.46 psia at 25 c =

Organisms that live in the alpine and taiga biomes have developed unique adaptations that aid in their survival. moss campion is one of the plants found in the alpine biome. it has small leaves and a cushion shape that protect it from the wind and freezing temperatures in the alpine. how has the moss campion adapted to enable its survival in the alpine biome? a. waxy needles b. cone-shaped c. thin trunks d. low-growing
