Varies depending on the city's water supply canals. The urban water supply consists entirely of groundwater, and the water temperature is low, usually 14 to 15 degrees. Some cities are all surface water, and the water temperature is high, generally 18 to 20 degrees.
The temperature of tap water is also affected by climate change. The water temperature is colder in winter and warmer in summer.
Generally speaking, tap water should be boiled to 100 degrees. It will taste better after boiling for a few minutes before drinking. If it is not boiled, it will not kill the microorganisms in the water that it needs. to cool and boil regularly. Good for health.
Extended content:Tap water refers to water produced after purification and disinfection in tap water treatment plants and whichmeets the corresponding standards for people's living and production use. Domestic water is mainly drawn from rivers, lakes, groundwater and surface water through the water intake pumping station of waterworks. Waterworks are treated in accordance with the “National Hygiene Standards for Drinking Water” and treated by processes such as. sedimentation, disinfection and filtration, and finally pass through the water distribution pumping station delivered to each user.

About the pressure generator
Customers often ask us the same question, which is to use the tap water instead of coolant. will corrode the water tank for the diesel generator? Regarding the explanation of this problem, our generator Jiangsu Taizhou Dongkang Co., Ltd. specially organized a technical teamEU to lead a discussion:
Tap water replacement coolant for generator sets is generally divided into the following types: 1. Well water 2. Tap water 3, water river. Generally, the main condensable tap water in remote areas is well water, while most customers in urban areas use tap water. The trace minerals in tap water themselves will not corrode the water tank! The cause of corrosion of the generator set fan cooling water tank is an electrochemical reaction. If it is made of real 304, 316L stainless steel and copper, it will not be corroded at all. the nickel content is insufficient and it will be used for a long time without adding chlorine. Pure water can also corrode! The material of the cooling water tank of ordinary domestic brand generator sets is geUsually made of 202 and 304 stainless steel. Generally, manufacturers use genuine 304 stainless steel materials, while many unscrupulous manufacturers use 202 stainless steel. As mentioned above, genuine 304 stainless steel does not will not corrode when used with tap water. However, after a long time, the chloride ions in tap water will ionize and turn the stainless steel a dark color. If 202 is used, corrosion will occur after prolonged washing and soaking. Therefore, we recommend customers to use at least pure water or tap water. Customers who have conditions can use vehicle coolant directly.

Pressure is a kind of potential energy to be converted into electrical energy, it needs to do work, it isi.e. convert potential energy into electrical energy. The so-called conversion means losing potential energy in order to obtain electrical energy, use your proposal, that is, water must flow, potential energy changes energy , then it becomes a rotational movement through the water turbine, driving the generator. to produce electricity. Theoretically speaking, water from the tap water pipe can power a small electricity-generating device, and experiments can therefore have little practical value.
