Flow Rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Flow Rate = Area of Cross-Section*Average Velocity
v_f = A*V_avg
This formula uses 3 Variables

Variables Used

Flow Rate - (Measured in Cubic Meter per Second) - Flow Rate is the amount of fluid that flows within a given time.
Area of Cross-Section - (Measured in Square Meter) - Area of Cross-Section MM is the enclosed surface area, product of length and breadth.
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

Area of Cross-Section: 0.05 Square Meter --> 0.05 Square Meter No Conversion Required
Average Velocity: 75 Meter per Second --> 75 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

v_f = A*V_avg --> 0.05*75

Evaluating ... ...

Liquid Level

Go Difference in Liquid Level = ((Capacitance-Capacitance with No Liquid Output)*Height)/(Capacitance with No Liquid Output*Magnetic Permeability)

Pipe Diameter

Go Diameter of Pipe = (Friction Factor*Length*(Average Velocity^2))/(2*Head Loss Due to Friction*Earth’s Geocentric Gravitational Constant)

Drag Coefficient of Pipe

Go Drag Coefficient = Force*(2*Acceleration Due to Gravity)/(Specific Weight Fluid*Area of Cross-Section*Velocity of Fluid)

Resisting Motion in fluid

Go Resisting Motion in Fluid = (Coefficient of Velocity*Area of Cross-Section*Velocity of Fluid)/Distance

Absolute Viscosity

Go Absolute Viscosity of Fluid = (Viscosity of Fluid*Diameter of Pipe*Density of Fluid)/Reynolds Number

Density of Liquid

Go Density of Fluid = Reynolds Number*Absolute Viscosity of Fluid/(Viscosity of Fluid*Diameter of Pipe)

Reynolds number of fluid flowing in Pipe

Go Reynolds Number = (Velocity of Fluid*Diameter of Pipe*Density of Fluid)/Absolute Viscosity of Fluid

Weight of Body in Liquid

Go Weight of Material = Weight of Air-(Immersed Depth*Specific Weight Fluid*Area of Cross-Section)

Float diameter

Go Diameter of Pipe = sqrt(4*Buoyancy Force/(Specific Weight Fluid*Length))

Cross-Sectional Area of Object

Go Area of Cross-Section = Buoyancy Force/(Immersed Depth*Specific Weight Fluid)

Immersed Depth

Go Immersed Depth = Buoyancy Force/(Area of Cross-Section*Specific Weight Fluid)

Buoyancy

Go Buoyancy Force = Immersed Depth*Area of Cross-Section*Specific Weight Fluid

Buoyancy Force on Cylindrical Displacer

Go Buoyancy Force = (Specific Weight Fluid*(Diameter of Pipe^2)*Length)/4

Length of displacer submerged in liquid

Go Length = 4*Buoyancy Force/(Specific Weight Fluid*(Diameter of Pipe^2))

Specific Weight of Liquid in Manometer

Go Pressure Difference = Specific Weight Fluid*Difference of Height of Liquid in Column

Height of liquid in column

Go Difference of Height of Liquid in Column = Pressure Difference/Specific Weight Fluid

Weight of Material on Length of Weighing Platform

Go Weight of Material = (Flow Rate*Length)/Speed of Body

Mass of Dry Air or Gas in Mixture

Go Mass of Gas = Mass of Water Vapor/Inside Humidity Ratio

Mass of Water Vapor in Mixture

Go Mass of Water Vapor = Inside Humidity Ratio*Mass of Gas

Flow Rate

Go Flow Rate = Area of Cross-Section*Average Velocity

Weight of Material in Container

Go Weight of Material = Volume*Specific Weight Fluid

Dynamic viscosity

Go Dynamic Viscosity of Fluid = Couple Moment/Force

Depth of Fluid

Go Depth = Change in Pressure/Specific Weight Fluid

Mass Flow Rate

Go Mass Flow Rate = Density of Fluid*Flow Rate

Volume of Material in Container

Go Volume = Area of Cross-Section*Depth

Flow Rate Formula

Flow Rate = Area of Cross-Section*Average Velocity
v_f = A*V_avg

What is normal flow rate?

Normal flow rate is 1 atmosphere (101.3 kPa) or 14.696 psi at 32 0F (0 0C). The actual flow rate is the actual volume of fluid that passes a given point based on the given pressure and temperature of the process.
