The maximum daily water consumption in a certain city is 100,000 m3/day. The water supply system includes a water intake pump room, transmission pipelines, a water treatment plant, a water supply pump room, clean water transmission pipes, a distribution network, and regulating tanks. The daily variation coefficient Kd is 1.2, and the hourly variation coefficient Kh is 1.5. The water used for the operations of the water treatment plant itself accounts for 5% of the total water volume. What is the designed flow rate of the water intake pump room in m3/h? Solution: The water pumping station is calculated based on the highest average daily flow rate, with the primary pumping station operating 24 hours a day; that is: Qd*Kh*(1+5%)/24 = 100000*1.5*1.05/24 = 6562.5 m3/h
The water intake pump house is designed based on the highest average daily flow rate, with the primary pump house operating 24 hours a day; that is: Qd × Kh × (1+5%) / 24 = 100,000 × 1.5 × 1.05 / 24 = 6562.5 m3/h
The water intake pump house is designed based on the highest average daily flow rate, with the primary pump house operating 24 hours a day; that is: Qd = Kh × (1+5%) / 24 = 100000 × 1.5 × 1.05 / 24 = 6562.5 m3/h
The water intake pump house is designed based on the highest average daily flow rate, with the primary pump house operating 24 hours a day; that is: Qd*Kh*(1+5%)/24 = 100000*1.5*1.05/24 = 6562.5 m3/h

Qd Kh (1+5%)/24=100000 *1.5 *1.05/24=6562.5m3/h
