168 pounds. To prevent geothermal pipes from freezing and cracking, approximately 0.21 kilograms of antifreeze are required for each meter. This can effectively ensure that geothermal pipes will not freeze and crack, and will not waste 0.21 times antifreeze. is equal to 84, converted to the unit of weight. It can be seen that 1 kilogram is equal to 2 kilograms and 84 kilograms is equal to 168 kilograms, so 168 kilograms of antifreeze are used for a 400 meter geothermal pipe.
No.
Under normal circumstances, it is relatively normal for antifreeze to consume approximately 10% to 35% of 10 liters per year. However, most of them are. Unnatural.
The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function.
