Question:
An air conditioner for an airport receives desert air at 45◦C, 10% relative humidity and must deliver it to the building at 20◦C, 50% relative humidity. The buildings have a cooling system with R-410a running with a high pressure of 3000 kPa and a low pressure of 1000 kPa, and their tap water is 18◦C. What should be done to the air? Find the needed heating/cooling per kg dry air.
Step by Step Answer:
The air needs to be cooled and dehumidified The cooling can be done either by evaporative cooling or ...View the full answer

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.
