Welcome to the Patient Resources Section of the Heart Rhythm Societyâs website. The Patient Resources section is intended to provide accurate and clear information about cardiac arrhythmia disorders. Although generalized and not intended to cover all aspects of any medical condition, a wide variety of information is available to you. Get started with the topic areas to your left to learn more.
When the sprinkler head is triggered, a valve to the pipe system is opened, releasing the water that is kept under pressure from the pipes. The water is quickly pushed out of the pipes through the sprinkler head, spraying water downward and out to the sides.
Differential head. We cannot tell you what discharge head a pump will provide unless you tell us the suction head (the head at the pump inlet). Think of a pump as adding head to your system. For example, imagine a pump that adds 20m head. If the head at the pump inlet is 5m then the discharge head will be 25m. The amount of head that the pump adds to the system is called the differential head. So, what we need to know is not what discharge head you require, but how much head would you like the pump to add to your system.
