Dry air at atmospheric pressure and 350 K, with a free stream velocity of 25 m/s,flows over
Question:
Dry air at atmospheric pressure and 350 K, with a free stream velocity of 25 m/s,flows over a smooth, porous plate 1 m long
(a) Assuming the plate to be saturated with liquid water at 350 K, estimate the mass rate of evaporation per unit width of the plate, n'A (kg/s ∙ m).
(b) For air and liquid water temperatures of 300, 325, and 350 K, generate plots of nA as a function of velocity for the range from 1 to 25 m/s.

In this video, the concept of pressure has been explained. The bottle is filled up with water, remove the pipe, and now you can see the clear flow of water from the holes due to liquid pressure.You can see that the second layer is holding the weight of the first layer and the third layer holding the weight of both upper layers, that’s why liquid flows out wider from the third as compared to the first two.At the first hole, water doesn’t roll along the walls; it flows out at an angle.At the second hole, you’ll see that the water flows out at a wider angle as compared to the first hole.At the third hole, we can see that the flow of water is much wider/greater than the other holes.This proves that the pressure at the bottom of the bottle is much more than the pressure at the top layers.
