Cubic feet per second (cfs):
* 1 cubic foot = 7.4805 gallons. * 1 cubic foot per second = 7.4805 gallons flowing by a particular point in 1 second. * 1 cfs = 1.983 acre-feet per day = 646,320 gallons = 2447 cubic meters of water. * 1 cfs is equivalent to 448.8 gallons of water flowing per minute.

Hereof, how do you convert CFS to MGD?

The answer is 0.64631688969744. We assume you are converting between million gallon/day [US] and cubic foot/second. You can view more details on each measurement unit: million gallon/day [US] or cfs The SI derived unit for volume flow rate is the cubic meter/second.

Additionally, how much is a cubic foot per second? Cusec is a measure of flow rate and is informal shorthand for "cubic feet per second" (28.317 litres per second).

Secondly, what is the formula for flow rate?

Q=Vt Q = V t , where V is the volume and t is the elapsed time. The SI unit for flow rate is m3/s, but a number of other units for Q are in common use. For example, the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min).

What does 1 CFS look like?

Cubic feet per second (cfs): * 1 cfs = 1.983 acre-feet per day = 646,320 gallons = 2447 cubic meters of water. * 1 cfs is equivalent to 448.8 gallons of water flowing per minute. * 1 cfs = 38.4 miner's inches of water.

### What is water velocity?

The speed at which water flows is called as the velocity of water. Flow rates are usually measured by the volume of water that passes each minute. This flow rate can be converted to velocity with the diameter of the pipe.

### How do you measure the velocity of a stream?

Use the Stream Flow Field Sheet to calculate surface velocity. Divide distance (20 feet) by average velocity time to get average surface velocity in feet per second. Next, multiply this result by the velocity correction factor of 0.8 to get average corrected velocity.

### How do you find the velocity?

To calculate velocity, divide distance traveled by the time it took to travel that distance and add direction. If one's position does not change, velocity is zero. Running in place does not change your position even if you are moving fast. Your velocity will be zero.

### What affects the velocity of a river?

The velocity of a river is determined by many factors, including the shape of its channel, the gradient of the slope that the river moves along, the volume of water that the river carries and the amount of friction caused by rough edges within the riverbed.

### How do you measure flow?

Flow may be measured by measuring the velocity of fluid over a known area. For very large flows, tracer methods may be used to deduce the flow rate from the change in concentration of a dye or radioisotope.

### What is stream velocity?

Stream velocity is the speed of the water in the stream. Units are distance per time (e.g., meters per second or feet per second). Stream velocity is greatest in midstream near the surface and is slowest along the stream bed and banks due to friction.

### What are five factors that determine the velocity of a stream?

Flow velocity is influenced by the slope of the surrounding terrain, the depth of the stream, the width of the stream, and the roughness of the substrate or stream bottom. If the surrounding terrain is steep, then rain water and snow melt will have less time to soak into the ground and runoff will be greater.

### How do you convert CFS to m3 s?

The answer is 35.314666212661. We assume you are converting between cubic foot/second and cubic metre/second. You can view more details on each measurement unit: cfs or m^3/s The SI derived unit for volume flow rate is the cubic meter/second. 1 cfs is equal to 0.028316847 cubic meter/second.

0.13 cubic feet

### How do you convert GPD to MGD?

Write down the number of gallons per day (GPD) that you want to convert. For example, 1020 GPD. Divide by 1,000,000. Observe the result, which is the equivalent number of millions of gallons per day.

### Does flow rate change with pipe size?

In general, the flow rate increases proportional to the square of the inside diameter, hence the flow rate is directly proportional to the area of pipe cross-section. The larger the diameter, the greater flow.

### Is flow rate constant?

For flow in a tube, the mass flow rate is a constant. For a constant density flow, if we can determine (or set) the velocity at some known area, the equation tells us the value of velocity for any other area.

### What is drop factor?

The drop factor is the number of drops in one mL of solution, and is printed on the IV tubing package. The formula for calculating the IV flow rate (drip rate) is… total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.

### Is pressure a force?

Pressure. Pressure is defined as force per unit area. It is usually more convenient to use pressure rather than force to describe the influences upon fluid behavior. The standard unit for pressure is the Pascal, which is a Newton per square meter.

### What is flow speed?

In continuum mechanics the flow velocity, also macroscopic velocity in fluid dynamics or drift velocity in electromagnetism, is a vector field used to mathematically describe the motion of a continuum. The length of the flow velocity vector is the flow speed and is a scalar.

### How do I find the volume?

Units of Measure
1. Volume = length x width x height.
2. You only need to know one side to figure out the volume of a cube.
3. The units of measure for volume are cubic units.
4. Volume is in three-dimensions.
5. You can multiply the sides in any order.
6. Which side you call length, width, or height doesn't matter.

### What are the factors that affect flow rate?

Fluid flow in pipes is affected by many different factors:
• The viscosity, density, and velocity of the fluid.
• Changes in the fluid temperature will change the viscosity & density of the fluid.
• The length, inner diameter, and in the case of turbulent flow, the internal roughness of the pipe.
