What is the flow rate in a pressure washer?
Flow rate is an important factor in pressure washers because it determines the amount of water that is being used to clean a surface. In simple terms, flow rate refers to the volume of water that flows through the pressure washer per unit of time. This is usually measured in the UK as L/ minutes .
When the flow rate is too low, the pressure washer may not be able to effectively remove dirt and grime from a surface. This is because the water may not have enough force to dislodge stubborn stains and debris. On the other hand, when the flow rate is too high, it can lead to wastage of water and energy, as well as potentially damaging the surface being cleaned.
Additionally, the flow rate plays a role in determining the overall cleaning efficiency of the pressure washer. A higher flow rate can help to flush away dirt and debris from the surface being cleaned, while a lower flow rate can allow the detergent to be more concentrated and effective.
Flow rate is important in a pressure washer because it affects the cleaning performance, efficiency, and effectiveness of the machine. It is important to consider the appropriate flow rate for the task at hand to ensure optimal results.
What is a good flow rate for a pressure washer?
The ideal flow rate for a pressure washer depends on the specific application and the pressure washer's specifications. Generally, a flow rate of 5.2 Liters per minute is suitable for light-duty tasks such as washing cars, boats, and outdoor furniture. For medium-duty tasks such as cleaning patios, decks, and fences, a flow rate of 6 to 9GPM is recommended.
For heavy-duty tasks such as cleaning concrete surfaces or heavily soiled areas, a flow rate of 11 to 15 L/m is typically necessary. However, it's important to note that using a high flow rate without adequate pressure can lead to poor cleaning performance.
Therefore, when choosing a pressure washer, it's important to consider both the flow rate and the pressure rating to ensure that the machine is capable of delivering the necessary cleaning power for the intended application. Additionally, it's essential to follow the manufacturer's guidelines and recommended flow rate to prevent damage to the pressure washer or the surface being cleaned.
