Area and volume calculation with the radius in LabVIEW, Calculate area of circle using LabVIEW, How to find area of cylinder in NI LabVIEW, LabVIEW to find area and volume of different shapes with the given radius, Find area and volume with the radius in NI LabVIEWHello friends! I hope you all will be absolutely and having fun. Today, I am going to share my knowledge with all of you on Area and Volume Calculation of different shapes with the given radius in NI LABVIEW. First of all I want to tell you that the area basically shows the space inside an object having two dimensions. Where as, Volume is the parameter which shows the space occupied by a three dimensional object.

So, we can roughly say that the volume is the area of a three dimensional object. For example you want to go for a trip and you have to pack your bags. So, in this case you have to make some space in your bag to put the clothes inside it. The space that you make for the clothes is basically an application of volume. We can also called it as a capacity of an object. Area is usually measured in and volume is measured in according to their System International (SI) units. In this tutorial we will do the area and volume Calculation of two different shapes, and they are circle and cylinder. Its just a simple LabView Project and the sole purpose of this project is to let you guys know how to do simple calculations in LabView. I hope you guys are gonna enjoy it. So, let’s get started with Area and Volume Calculations in LabView:

Area and Volume Calculation in LabVIEW

Here I am going to elaborate you about the different formulas to calculate the area and volume of the different shapes e.g. circle, cylinder, square, triangle etc. I will focus to calculate the area and volume of two different shapes with the given radius. The basic formulas for the area and volume of the square or rectangle are given below.

  • Area = length × width
  • Volume = length × width × height

But we will find the area and volume of circle and cylinder with the given radius. You can use the formulas given below for the area and volume calculation with the given radius.

  • Area of circle = πr²
  • Area of cylinder = 4πr²
  • Volume of cylinder = (4/3)πr³

Youn can download a complete NI LabVIEW simulation here.

I am using above formulas to calculate these parameters using NI LabVIEW. I will make a very simple program in NI LabVIEW which will take radius as an input and calculates the area and volume of circle and cylinder after manipulating the given area. You can also select the maximum limit of the radius. When the radius approaches its maximum limit an LED will glow showing the notification reduce the radius. So, let’s start with the NI LabVIEW to make this program for Area and Volume Calculation.

Steps to Follow
  • Go to the Front Panel and Right Click on it.
  • Go to Controls-> Silver-> Numeric, you can see different numeric blocks here e.g. numeric control, numeric indicator etc.
  • Choose the encircled block shown in the below.
