More specifically, water discharge, which is the volume of water moving through the cross section of a stream or river during a particular unit of time, is typically computed by
multiplying the area of water in a channel cross section by the average velocity of the water in that cross section
.
What is the formula for discharge through the pipe?
From cross-section and average speed. The flow rate of a stream is equal to the flow velocity (speed) multiplied by the cross-sectional area of the flow. The equation
Q=AV (Q=discharge rate, A=area, V=velocity)
is sometimes known as the discharge equation.
How do you calculate discharge?
To calculate discharge,
multiply the area of water in a channel cross section by the average velocity of water in that cross section
. The simplest way to measure discharge is to divide the channel cross section into vertical rectangular subsections.
What is rate of discharge?
The discharge rate is defined as
the steady current in amperes (A) that can be taken from a battery of defined capacity (Ah) over a defined period (h)
. … Batteries for CEGB power stations are normally specified for a 10-hour rate.
How do you calculate water discharge rate?
More specifically, water discharge, which is the volume of water moving through the cross section of a stream or river during a particular unit of time, is typically computed by
multiplying the area of water in a channel cross section by the average velocity of the water in that cross section
.
How is monthly discharge calculated?
Monthly Average (Average monthly discharge limitation) – The highest allowable average of daily discharges (mg/L, lbs or gallons) over a calendar month, calculated as
the sum of all daily discharges (mg/L, lbs or gallons) measured during a calendar month divided by the number of daily discharges measured during that
…
What is the difference between flow rate and discharge?
The amount of fluid passing a section of a stream in unit time is called the discharge. If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by
Q = Av
which is known as volume flow rate.
How do you calculate the volume of a water discharge from a pipe?
For a pipe use its length instead of height:
pipe volume = π * radius2 * length
, where radius = inner diameter/2 . The volume of a pipe is equal to the volume of a liquid inside (if a pipe is fully filled with it).
What is discharge in pipe?
discharge pipe –
a pipe through which fluids can be discharged
. hydrant – a discharge pipe with a valve and spout at which water may be drawn from the mains of waterworks. pipage, pipe, piping – a long tube made of metal or plastic that is used to carry water or oil or gas etc.
What is discharge in FM?
Discharge (also called flow rate)
The amount of fluid passing a section of a stream in unit time
is called the discharge.
What does discharge mean in rivers?
Discharge is
the volume of water moving down a stream or river per unit of time
, commonly expressed in cubic feet per second or gallons per day.
How do you calculate mean flow?
Calculation of the mean flow may often be as simple as the mathematical mean:
simply add up the given flow rates and then divide the final figure by the number of initial readings
. For example, given two discharges (Q) of 3 m3/s and 5 m3/s, we can use these flow rates Q to calculate the mean flow rate Q
mean
.
What means annual discharge?
3.9 Mean Annual Discharge and Discharge Variability. Page 1. In hydrology and water management, the term discharge refers to the volume of
water
which flows through a defined cross-section of a watercourse per unit of time. Depending on the size of the river or stream, the discharge is measured either in m3/s or l/s.
What is long term median flow?
The long-term median flow for the month is
the 50 percent exceedence flow in the period of record
, determined by ranking the monthly mean flow values for the same calendar month from throughout the years of record; for the given month, the median flow value is such that half of the previously recorded monthly mean flow …
Why is my discharge like water?
It’s
caused by hormonal changes
. If the discharge is watery, it’s most likely normal and not a sign of infection. Clear and watery discharge can increase at any point during your cycle. Estrogen can stimulate the production of more fluids.
What is discharge per unit time?
Discharge is
the volume of water moving down a stream or river per unit of time
, commonly expressed in cubic feet per second or gallons per day.
