The highest amount of stream of river flow occurring in a year, or from a single storm event.
The maximum flow expected to enter a facility.
The very fastest you can move air by blowing out as hard as you can. This measurement correlates pretty well with FEV-1 (a measurement obtained through spirometry in a doctor's office) but doesn't require expensive equipment and can be obtained easily at home with a peak flow meter.
The maximum instantaneous rate of flow during a storm or other period of time.
The speed at which you can blow air out of your lungs. You can test this at home or in the healthcare provider's office using a peak flow meter.
maximum flow through a watercourse which will recur with a stated frequency. The maximum flow for a given frequency may be based on measured data, calculated using statistical analysis of peak flow data, or calculated using hydrologic analysis techniques. Projected peak flows are used in the design of culverts, bridges, and dam spillways.
Refers to a specific period of time when the discharge of a stream or river is at its highest point.
in a wastewater treatment plant, the highest flow expected to be encoutered under any operational conditions, including periods of high rainfall and prolonged periods of wet weather.
A measurement of how well you can blow air out of your lungs. If your airways become narrow and blocked due to asthma, you can't blow air out as well, and your peak flow values drop. Peak flow is measured at home with a small, inexpensive plastic meter.
the maximum volume of water that is carried in the river over a certain period of time, expressed in cfs. Peak flows are described in terms of rainfall event frequencies. For example, the "100-year peak flow" has a 1% chance of occurring in any given year.
the maximum flow rate of air breathed out
The maximum rate of flow through a watercourse for a given storm
The greatest flow attained during melting of winter snowpack or during a large precipitation event.
Maximum momentary stage or discharge of a stream in flood. Design Discharge.
the maximum instantaneous discharge of a stream or river at a given location. It usually occurs at or near the time of maximum stage.
The maximum speed at which someone can breathe out air from the lungs. Peak flow can be measured using a number of different devices, including a portable one called a peak flow meter. How fast air goes out depends on how hard one tries and usually happens in the first second of blowing out.
A measure of how fast you can blow air out of your lungs. In asthma, your peak flow reflects the extent to which your bronchial tubes are normally open or abnormally narrowed (see Asthma).
