When the water supply volume per hour of the primary pump station and the secondary pump station is similar, the regulating capacity of the clear water tank can (); at this time, in order to adjust the difference between the water supply volume from the secondary pump station and the water demand of users, the regulating capacity of the water tower will (). a. Reduce ； Reduce b, increase ； Increase c, increase ； Reduce d, reduce ； Increase Answer: d. The regulating function of the clear water tank is to adjust the difference in water supply volume between the primary pump station and the secondary pump station; when the hourly water supply volumes of these two stations are similar, the regulating capacity of the clear water tank decreases. At the same time, due to the uniform water supply from the primary pump station, the difference between the water supply volume from the primary and secondary pump stations and the users’ water consumption is large, which increases the regulating capacity of the water tower.
