flow

a measurement of quantity over a specified period of time. Unlike a STOCK, which is not a function of time, a flow measures quantity passing per minute, hour, day or whatever. A common analogy is to a reservoir. The water entering and leaving the reservoir is a flow but the water actually in the reservoir at any one point in time is a stock. INCOME is a flow but WEALTH is a stock.

Lung function test and peak flow measurement were done in only 18(24%) and 25 (33%) of patients, respectively.
The researchers found that the most effective case-finding tools were the peak flow meter alone, the peak flow meter plus WheezoMeter, and microspirometry alone.
The company's AsthmaMDTM Peak Flow Meter has been developed to be used with the AsthmaMDTM smartphone app, which enables asthma patients to create a digital journal of their asthma activity, digitally logging peak flow meter readings, and tracking symptoms, medications and notes.
Similar to the Village Creek Peak Flow Storage project in Fort Worth, McCarthy completed the Tarrant Regional Water District Constructed Wetlands — a $42 million CMAR project that created 1,300 acres of wetlands near the Richland-Chambers Reservoir near Corsicana, Texas, and is the second largest constructed wetlands in the United States.
This means that no terrestrial invertebrates were reported for those streams for 120, 144, and 168 h after peak flow. In the Rio Puerco watershed, however, flows in some streams continued <168 h after peak flow, and the earliest that flows ceased was at 96 h.
Variation of Annual Maximum Peak Flow. The annual maximum peak flow was derived from the daily runoff data collected between June and November from 1959 to 2005.

A spirometer and peak flow meter are used to diagnose as well as monitor chronic obstructive pulmonary disorders like asthma.
Rainstorm characteristics are variant spatially and temporally [15] which is defined as the rainstorm movement and in turn affects peak flow. In many hydrological studies assume that rainstorm characteristics are constant during the arrival and occurrence of rainstorm.
Only 23% reported measuring peak flow, which is suggested as a method for assessing lung function in asthma patients.
