The alkali formula for the concentration of alkali tanks
Thread Content
Hello everyone, our factory will resume production this year. I forgot about the alkali formula for mixing the concentration of the alkali tank. It looks like this. It is known that the alkali concentration of the finished product is 32.20 and the liquid level is 4 meters (1 meter is 50 cubic meters = 65.5 tons). How much caustic soda with a concentration of 31.19 is used to configure a low-concentration alkali with a concentration of 32.05? This is high with low. Another way is to mix low with high, that is, mix caustic soda with a concentration of 31.19 into 32.05, and the liquid level is still 4 meters. Use a high concentration of 32.20 to prepare it. How much high concentration caustic soda is needed? (Don’t think about whether it can be installed, just explain the data formula in detail). Thank you everyone
It seems that the expression of difficulty is wrong.
The first type: x=(32.2-32.05) * 200/(32.05-31.19) Second type: x=（32.05-31.19） * 200/(32.2-32.05)
relive* The first question of the linear equation of two variables in junior high school: It is known that the alkali concentration of the finished product is 32.20 and the liquid level is 4 meters (1 meter is 50 cubic meters = 65.5 tons). How much caustic soda with a concentration of 31.19 is needed to prepare a low-concentration alkali with a concentration of 32.05? Assume that 31.19% of caustic soda is required as: x=(32.2-32.05) * 200/(32.05-31.19) :lol:lol:lol:lol:lol
The premise of this calculation method is that the density is approximately the same and the volume change is ignored. :lol:lol:lol:lol
