How many transverse or longitudinal vertical baffles should a water tank have?

The recommended number of transverse or longitudinal vertical baffles in a water tank is two. Baffles serve an essential role in improving the flow characteristics and operational efficiency of a water tank. By incorporating two baffles, the water is encouraged to move more smoothly, reducing turbulence and promoting better mixing and settling of particulates. This configuration helps in maintaining water quality and optimizing the tank's capacity.

Having a baffle system with two baffles strikes a balance, providing sufficient support against wave action while still allowing for effective circulation and reducing stagnation zones. This design is often used in practice to achieve the desired hydraulic performance within the tank.
