Final answer:
Surge tanks placed above ground should be located in a position that allows for easy maintenance, access, and monitoring. They should also be placed at a point where the pressure changes will be most severe, such as high points or locations with significant changes in elevation.
Step-by-step explanation:
Surge tanks are used in hydraulic systems to deal with sudden changes in pressure and prevent damage to the system. While surge tanks are typically placed underground, there are situations where they may need to be placed above ground. When placing surge tanks above ground, they should be located in a position that allows for easy maintenance, access, and monitoring.
One important consideration when placing surge tanks above ground is that they should be placed at a point where the pressure changes will be most severe. For example, in a pipeline system, surge tanks are generally placed at high points or at locations where there are significant changes in elevation. This ensures that the surge tank can effectively absorb and release pressure during transient events.
Another factor to consider is the structural support required for an above-ground surge tank. These tanks can be quite large and heavy, so they need to be placed on a stable foundation and secured properly to prevent any safety hazards. It's also important to ensure that the tank is designed to withstand weather conditions and potential impacts.
