In the lab you will calculate a liquid amine volumetric flow rate based on the action of a piston pump. A piston pump is a type of positive displacement pump, which delivers a fixed volume of liquid with every pump stroke. Every pump stroke delivers a cylinder of liquid. You can determine the volumetric flow rate by measure the volume of the piston (often it is posted on the pump) and count pump strokes over a period of time. Suppose a piston pump has one cylinder with a volume of 0.1 L. You count 25 pump strokes over 15 seconds. What is the volumetric flow rate in units of L/h? (type in only the number, without the units)
