Variables Used

Specific Force in OCF - (Measured in Cubic Meter) - Specific Force in OCF (open channel) is dependent on discharge and cross sectional area.
Discharge of Channel - (Measured in Cubic Meter per Second) - Discharge of Channel is the rate of flow of a liquid.
Cross-Sectional Area of Channel - (Measured in Square Meter) - Cross-Sectional Area of Channel is the area of a two-dimensional shape that is obtained when a three-dimensional shape is sliced perpendicular to some specified axis at a point.
Distance from Centroidal - (Measured in Meter) - Distance from Centroidal is the average distance between all points and the central point.

STEP 1: Convert Input(s) to Base Unit

Discharge of Channel: 14 Cubic Meter per Second --> 14 Cubic Meter per Second No Conversion Required
Cross-Sectional Area of Channel: 15 Square Meter --> 15 Square Meter No Conversion Required

Vertical Depth of Centroid of Area given Specific Force

Go Distance from Centroidal = (Specific Force in OCF-(Discharge of Channel*Discharge of Channel/(Cross-Sectional Area of Channel*[g])))/Cross-Sectional Area of Channel

Specific Force

Go Specific Force in OCF = (Discharge of Channel*Discharge of Channel/(Cross-Sectional Area of Channel*[g]))+Cross-Sectional Area of Channel*Distance from Centroidal

Vertical Depth of Centroid of Area given Specific Force with Top Width

Go Distance from Centroidal = (Specific Force in OCF-(Cross-Sectional Area of Channel^2/(Top Width)))/Cross-Sectional Area of Channel

Specific Force given Top Width

Go Specific Force in OCF = ((Cross-Sectional Area of Channel^2)/Top Width)+Cross-Sectional Area of Channel*Distance from Centroidal

Top Width given Specific Force

Go Top Width = (Cross-Sectional Area of Channel^2)/(Specific Force in OCF-Cross-Sectional Area of Channel*Distance from Centroidal)

Specific Force Formula

Specific Force in OCF = (Discharge of Channel*Discharge of Channel/(Cross-Sectional Area of Channel*[g]))+Cross-Sectional Area of Channel*Distance from Centroidal
F = (Q*Q/(A_cs*[g]))+A_cs*Y_t

What is Rate of flow?

In physics and engineering, in particular fluid dynamics, the volumetric flow rate is the volume of fluid which passes per unit time; usually it is represented by the symbol Q. The SI unit is cubic metres per second. Another unit used is standard cubic centimetres per minute. In hydrometry, it is known as discharge.

How to Calculate Specific Force?

Specific Force calculator uses Specific Force in OCF = (Discharge of Channel*Discharge of Channel/(Cross-Sectional Area of Channel*[g]))+Cross-Sectional Area of Channel*Distance from Centroidal to calculate the Specific Force in OCF, The Specific Force is defined as the non-gravitational force per unit mass. Specific force (also called g-force and mass-specific force) is measured in meters/second² (m·s−2) which is the units for acceleration. Thus, specific force is not actually a force, but a type of acceleration. Specific Force in OCF is denoted by F symbol.

How to calculate Specific Force using this online calculator? To use this online calculator for Specific Force, enter Discharge of Channel (Q), Cross-Sectional Area of Channel (A_cs) & Distance from Centroidal (Y_t) and hit the calculate button. Here is how the Specific Force calculation can be explained with given input values -> 74.55836 = (14*14/(15*[g]))+15*20.2.

FAQ

What is Specific Force?

The Specific Force is defined as the non-gravitational force per unit mass. Specific force (also called g-force and mass-specific force) is measured in meters/second² (m·s−2) which is the units for acceleration. Thus, specific force is not actually a force, but a type of acceleration and is represented as F = (Q*Q/(A_cs*[g]))+A_cs*Y_t or Specific Force in OCF = (Discharge of Channel*Discharge of Channel/(Cross-Sectional Area of Channel*[g]))+Cross-Sectional Area of Channel*Distance from Centroidal. Discharge of Channel is the rate of flow of a liquid, Cross-Sectional Area of Channel is the area of a two-dimensional shape that is obtained when a three-dimensional shape is sliced perpendicular to some specified axis at a point & Distance from Centroidal is the average distance between all points and the central point.

How to calculate Specific Force?

The Specific Force is defined as the non-gravitational force per unit mass. Specific force (also called g-force and mass-specific force) is measured in meters/second² (m·s−2) which is the units for acceleration. Thus, specific force is not actually a force, but a type of acceleration is calculated using Specific Force in OCF = (Discharge of Channel*Discharge of Channel/(Cross-Sectional Area of Channel*[g]))+Cross-Sectional Area of Channel*Distance from Centroidal. To calculate Specific Force, you need Discharge of Channel (Q), Cross-Sectional Area of Channel (A_cs) & Distance from Centroidal (Y_t). With our tool, you need to enter the respective value for Discharge of Channel, Cross-Sectional Area of Channel & Distance from Centroidal and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Specific Force in OCF?

In this formula, Specific Force in OCF uses Discharge of Channel, Cross-Sectional Area of Channel & Distance from Centroidal. We can use 1 other way(s) to calculate the same, which is/are as follows -

Specific Force in OCF = ((Cross-Sectional Area of Channel^2)/Top Width)+Cross-Sectional Area of Channel*Distance from Centroidal
