Rate of Flow Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rate of Flow = Cross-Sectional Area*Average Velocity
Q_f = A_cs*V_avg
This formula uses 3 Variables

Variables Used

Rate of Flow - (Measured in Cubic Meter per Second) - Rate of Flow is the rate at which a liquid or other substance flows through a particular channel, pipe, etc.
Cross-Sectional Area - (Measured in Square Meter) - Cross-Sectional Area 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.
Average Velocity - (Measured in Meter per Second) - Average Velocity is defined as the mean of all different velocities.

STEP 1: Convert Input(s) to Base Unit

Cross-Sectional Area: 1.3 Square Meter --> 1.3 Square Meter No Conversion Required
Average Velocity: 18.54 Meter per Second --> 18.54 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_f = A_cs*V_avg --> 1.3*18.54

Evaluating ... ...

Q_f = 24.102

STEP 3: Convert Result to Output's Unit

24.102 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

24.102 Cubic Meter per Second <-- Rate of Flow

What is rate of 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 the volume flow rate. Discharge is also expressed as mass flow rate and weight flow rate.

How to Calculate Rate of Flow?

Rate of Flow calculator uses Rate of Flow = Cross-Sectional Area*Average Velocity to calculate the Rate of Flow, Rate of flow (or) Discharge is the rate at which a liquid or other substance flows through a particular channel, pipe, etc. Rate of Flow is denoted by Q_f symbol.

How to calculate Rate of Flow using this online calculator? To use this online calculator for Rate of Flow, enter Cross-Sectional Area (A_cs) & Average Velocity (V_avg) and hit the calculate button. Here is how the Rate of Flow calculation can be explained with given input values -> 24.0006 = 1.3*18.54.

FAQ

What is Rate of Flow?

Rate of flow (or) Discharge is the rate at which a liquid or other substance flows through a particular channel, pipe, etc and is represented as Q_f = A_cs*V_avg or Rate of Flow = Cross-Sectional Area*Average Velocity. Cross-Sectional Area 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 & Average Velocity is defined as the mean of all different velocities.

How to calculate Rate of Flow?

Rate of flow (or) Discharge is the rate at which a liquid or other substance flows through a particular channel, pipe, etc is calculated using Rate of Flow = Cross-Sectional Area*Average Velocity. To calculate Rate of Flow, you need Cross-Sectional Area (A_cs) & Average Velocity (V_avg). With our tool, you need to enter the respective value for Cross-Sectional Area & Average Velocity 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 Rate of Flow?

In this formula, Rate of Flow uses Cross-Sectional Area & Average Velocity. We can use 2 other way(s) to calculate the same, which is/are as follows -

Rate of Flow = Head Loss of Fluid*Specific Weight*pi*(Diameter of Pipe^4)/(128*Viscous Force*Length of Pipe)
Rate of Flow = Power/(Specific Weight of Liquid*(Total Head at Entrance-Head Loss of Fluid))
