|---|---|
| Float Valve | A float valve is a simple controller to which responds to changes in fluid level. It can also be called a liquid level controller. The float valve will open or close according to its required use. |
| Flooded Suction | Flooded suction in pumps refers to the liquid flowing to the pump inlet from a higher source meaning it is gravity fed. |
| Flow rate | A pumps flow rate is the measurement of the volume of liquid the pump is capable of in a given time frame. Identified on a pumps specifications the maximum capacity flow rate of the pump is commonly measured in litres per minute (L/min), litres per second (L/sec) or metres³ an hour (m³/hr). |
| Foot Valve | A foot valve is a valve used in plumbing and commonly used in conjunction with pumps to allow a solution to flow in one direction only. A foot valve is also known as a check valve. |
| Friction Loss | Friction loss is the loss of energy or “head” that occurs in pipe flow due to viscous effects generated by the surface of the pipe. Friction Loss is considered as a “major loss”. |
