2. Estimate the value of mass transfer coefficients, kc and kG, in large of stream of air at 273K flowing in a duct past the flat plate of solid naphthalene with length of 40 cm. The velocity of the air is 0.82 m/s at 273K and 1 atm abs. The diffusion coefficient of naphthalene in air at 273K and 1 atm abs is 5.16x10-6 m2 /s

the one with the highest speed

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.

explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
