Web2 hours ago · I have created a table to show the average daily volume over the last 3 months (63 days). Of course for a new IPO, a stock will have less than 63 trading days so far - in this case the table shows "NaN" Is there a way to show the average volume for last 3 months if available, and if not then average over bars that ARE available? Many metering pumps are piston-driven. Piston pumps are positive displacement pumps which can be designed to pump at practically constant flow rates (averaged over time) against a wide range of discharge pressure, including high discharge pressures of thousands of psi. Piston-driven metering pumps commonly work as follows: There is a piston (so…

WebPump capacity is expressed in volumetric flow rate and head. It is measure in m 3 /s or ft 3 /s.
