Rice is drained after cooking to remove any excess water that may be left in the pot. This helps prevent the rice from becoming mushy or overly wet. Draining the rice also helps to separate the grains, making them light and fluffy. Additionally, draining the rice can help to remove any excess starch, resulting in a better texture and flavor. **

When venting a heating system, a small amount of water is drained in order to remove any air pockets that may have accumulated in the system. This water is typically a small fraction of the total water volume in the system, and is only drained temporarily during the venting process. It is important to ensure that the proper amount of water is maintained in the system after venting to ensure proper operation and prevent damage to the system. **

The drained weight refers to the weight of a food product after the liquid or brine has been removed. This is commonly used for canned goods such as fruits, vegetables, and seafood.

It is often listed on the packaging of canned goods to provide consumers with accurate information about the quantity of the food product. **

Roof surfaces are typically drained through a system of gutters and downspouts. Gutters are installed along the edges of the roof to collect rainwater and direct it towards the downspouts. The downspouts then carry the water down to the ground and away from the building's foundation. Proper drainage is essential to prevent water damage to the roof and the building's structure. Additionally, some roofs may have built-in slope or pitch to help direct water towards the gutters and away from the roof surface. **

Rainwater is drained under asphalt through a system of underground pipes and drains. These pipes are typically installed during the construction of the asphalt surface and are designed to collect and redirect rainwater away from the surface to prevent pooling and flooding. The pipes are connected to a network of stormwater drains that ultimately lead to a drainage system or natural water source. Proper drainage is essential to maintain the integrity and longevity of the asphalt surface. **
