Parts Per Million to Percent Converter Parts Per Million to Percent Converter

Use this conversion calculator to convert a PPM value (Parts Per Million) to a percentage value. You can also convert a percentage value to a PPM value. This conversion calculator has been built in php. There is no requirement to load any plug in.

Pipe or Tube Flow Conversion Calculator Pipe or Tube Flow Conversion Calculator

This online conversion calculator will determine the flow rate in a fluid across an orifice plate . The orifice plate acts as a restriction to the flow and creates a differential pressure. From the pressure drop /differential pressure and with details of the pipe dimensions and orifice plate sizing the flow rate of the liquid or gas can easily be determined

 Flow Conversion Calculator for a Venturi Flow Conversion Calculator for a Venturi

The Venturi  is also a device using Differential Pressure methods to calculate the flow rate. These are based on Bernoulli equations. The pressure drop across a venturi is lower than that of an orifice plate. The conversion calculator will enable you to make a flow calculation based on certain inputs requested.

Pitot Probe –  Pitot Static Tube Calculator Pitot Probe – Pitot Static Tube Calculator

The Pitot Static Tube sometimes referred to as a Pitot Tube is a differential pressure device used as a flow meter for gases and liquids.  It uses a differential pressure principle for the measurement using the known or measured static pressure and total pressure differences know as the dynamic pressure. Pressure can be measured using a manometer or pressure transmitter. This flow metering device is also known as the Prandtl Tube.

Kinematic Viscosity Calculation Kinematic Viscosity Calculation

In order to calculate Kinematic viscosity in flow, the density must be known . Use this program to easily calculate the kinematic viscosity of a fluid with a known density . The program covers all the common absolute viscosity units and density units as well as common kinematic viscosity units . You also use the conversion calculator to simply convert between viscosity units
