How much water is left in the sink in an hour?

One side of water. The domestic water pressure is generally 0.25Mpa, and the hourly flow is about 1.3m? About. Per-minute flow standard under corresponding technical pressure. For example, according to the standard of China, under the pressure of 3 kg, that is, below 0.3 MPa, the flow rate of basin faucet is 12, which means that the flow rate per minute exceeds 12 liter of water. Generally, it is 15 liter of water per minute. One cubic meter = 1000 liter, so it is 1000/ 15=66.67 minutes 1 hour.
