There is severe heat all over the country including the capital Delhi. Due to the heat, the situation is such that the temperature of some states and cities is reaching between 45 to 50 degrees. Due to the severe heat, the situation is that people are not coming out of their homes. But the question is that in such heat, does pouring water on the roof in the evening reduce the temperature of the house? Or does the temperature increase. Today we will tell you the science behind this.
Temperature of the house
Due to heat, the temperature of the house also increases. Not only this, you cannot go to the roof of the house barefoot, because the roof is so hot that the feet get burnt. Due to the heat of the roof, the temperature inside the house also increases. You must have realized that the temperature of the room below the roof is the highest, while the temperature of the room below is low. At the same time, whenever we sprinkle water on the roof, it turns into steam and in this process the ground absorbs the heat. However, this makes the environment around and below a little cool. The air that comes down from the wet roof is slightly cool. This reduces the temperature inside the house and people feel cool.
How will the temperature be reduced
Now the question is how can the temperature of the house be reduced during summer. Let us tell you that sprinkling water on the roof in the evening can cool the house. Not only this, it can reduce the temperature by 2-3 degrees Celsius. Apart from this, evaporation cooling takes less energy than air conditioning. This makes it easier to breathe in hot air. Sprinkling water on the roof is a good way to reduce heat. You must have seen that during summer most people sprinkle water on the roof and in front of the house. This causes a slight drop in temperature.
How much water is right to use
It is important to keep the quantity in mind before sprinkling water at any place. If you spray more water to cool the house, it can damage the roof and cause dampness in the houses. Therefore, water should be sprinkled on the roof in a prescribed amount so that water does not stagnate on the roof. Otherwise, it can cause heavy damage to the roof.
