“难度”应该是少于 75 ppm ;碳酸盐 ( 例如 CaCO 3) 应该是少于 45 ppm ;被解散固体应该是少于 75 ppm ;以及氯化物和 sulfates 应该是少于 25 ppm 作为建议。 翻译结果3复制译文编辑译文朗读译文返回顶部 "硬度"应小于 75 ppm ;碳酸盐 (如 CaCO 3) 应小于 45 ppm ;溶解的固体应小于 75 ppm ;和氯...
The hardness of water is measured in the units mg/L (milligrams per liter), ppm (parts per million), or mmol/L (millimoles per liter). The formula to calculate the hardness of water (in mg/L) can be written as: Hardness=2.497Cal+4.118MgHardness=2.497Cal+4.118Mg where Cal and Mg ...
Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon. For example, say you have a water hardness value of 180 ppm. Work out 180 ÷ 17.1 = 10.526 Round the result to one decimal place, the same de...
