Basic Knowledge
Flow Rate Unit Conversion
Flow rate is expressed as the volume flowing per unit time. The typical units are L/min (liters per minute) and m³/h (cubic meters per hour). 1 m³/h is equivalent to approximately 16.67 L/min.
What is Viscosity
Viscosity is a quantity that represents how difficult a liquid is to flow or its degree of stickiness, with the SI unit being pascal second (Pa·s). The larger the value, the more resistant the liquid is to flow; for example, honey has much higher viscosity than water at room temperature.
