Orifice Plate Calculator
Density Calculator Orifice plate pressure drop calculator is used for flow rate measuring in pipe systems. With orifice plate, pressure drop is created. Based on the magnitude of pressure drop, flow rate can be calculated. The pressure drop calculation formula for the pipe is explained in more detail below .Practical for larger tube diameters and for dirty fluid where other methods are impractical.

Solid Flow Calculator
Solid Flow Calculator

This Solids Flow calculator has been designed to help someone who is using some sort of conveyor system to move the solids. For solid objects, the flow usually is described by a specification of the mass or weight per unit time that is being transported by the conveyor system. The units will be in many forms, for example, kg/min or Ib/min.

Pitot Static Tube Online Calculation for Compressible and Incompressible Flow and Liquid
Pitot Static Tube Online Calculation  for Compressible  and Incompressible Flow and Liquid The Pitot Static Tube sometimes referred to as a Pitot Probe 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.
