Applications of Venturi Meter. In this chapter we will discuss basics of a refrigeration cycle mainly vapor compression cycle main concept parts components working principle along with a real example etc. A flow nozzle which is held between flanges of pipe carrying the fluid whose flow rate is being measured.

Chemical Engineering World CEW Chemical Engineering World CEW Chemical Engineering World is a Leading community in world whos related to Chemical industries Pharmaceuticals Refinery Power plant Offshore. From Coriolis flow meters to magnetic flow meters we offer a comprehensive industry-leading portfolio of flow measurement devices. This pressure drop is measured using a differential pressure sensor and when calibrated this pressure drop becomes a measure of flow rate.

Mathematics probability and statistics engineering sciences materials. The jet ejector package the nozzle venturi and various connections is often separate from the pump before installation. The venturi meter is a flow meter that used where high-pressure recovery is required.

Venturi tubes are more expensive to construct than simple orifice plates and both function on the same basic principle. Heat Recovery Steam Generator HRSG Heat Recovery Steam Generator HRSG Heat Recovery Steam Generator HRSG Heat recovery steam generators are equipments which are used to extract heat from process gas or a waste gas streams and use that heat to convert liquid water into steam in order to use that steam in some other process or the HSRG is made. The head over the weir is measured and can be used to calculate the water flow rate over the rectangular weir and through the open channel.

Exam consists of 110 questions over these topic areas. Venturi meter has a limitation and that is Its low Reynolds number of 150000. There is a limitation that the diameter which is around 80mm or less than 80 mm can not use venturi meter.

991 Reformatted 195. Openings are provided at two places 1 and 2 for attaching a differential pressure sensor u-tube manometer differential pressure gauge etc as show in the diagram. Flow Wedge Meter Target Meter Weir Meter Ultrasonic Meter V-cone Meter Quick Change Pitot Tube Rotometer Double Steam Traced Venturi And Gate Vortex Sensor Flowmeter Venturi Meter Turbine Meter Not Gate Or Gate Correcting Element Diamond Pressure Gauges.

Because of the sudden contraction at the orifice and the subsequent sudden expansion after the orifice the coefficient of discharge C for the orifice meter is much lower. Diagram of a Parshall flume showing free-flow and submerged flow operating regimes A modified version of the Venturi flume is the Parshall flume. By employing the continuity equation and Bernoullis principle the volumetric flow rate through the orifice meter can be calculated as described previously for venturi meter.

The 6-hour chemical engineering FE. The flow of chemicals in pipelines. Visit the NCEES FE website or the NCEES YouTube channel for details.

Calculating the flow rate of fluid that is discharged through the pipe. 4-Stroke Air-Cooled V-Twin Gasoline Engine. All the files below are presented in PDF format or DWG.

Part III - General Material. Below is a chart that will allow the correct selection of main venturi size for engines given the engines capacity and the RPM at which peak power is realistically expected to be achieved for road engines peak power is usually between 5250 and 6500 depending on the cam selectionAfter the correct venturi size has been arrived at it is a simple matter to determine. INTRODUCTION TO FLUID FLOW 12 Fluids 121 What is a Fluid.

The following application of Venturi meter is. Two common types of sharp crested rectangular weir are the suppressed rectangular weir and the. Part V - Appendices.

Fh500v Fh531v Fh580v Fh601v Fh641v Fh661v Fh680v Fh721v Fh541v. It uses a variable throat venturi meter which has a wide range for flowrate measurement. Magnetic Flow Meter or Electromagnetic Flow Meter.

Hence 3 8 6 5 6. Generally matter exists in many one of four fundamental states though there are many. Venturi tubes are often used in processes where permanent pressure loss is not tolerable and where maximum accuracy is needed in case of highly viscous liquids.

Part II - General Provisions. The pressure difference between section 1 with the full flow and section 2 at the throat can then be used to measure the liquid flow rate using equations developed earlier for the venturi meter and the flow nozzle. The refrigeration cycle is the main basic cycle for all air conditioning and refrigeration equipment.

Thats why weve broken down each flow meter type for you so you can decide which type of meter is the best for your unique application. The expanded size of the flow meter tubes slows the flow of the fluid that creates a pressure drop from when the fluid enters the flow and when it exits. An electronic reference booklet of equations and constants is supplied at the beginning of the exam.

The FE exam is a computer-based test. Flow Meter requirements vary from mass flow to volume flow and beyond. Orifice meter Working of Orifice Meter.

When a venturi flow meter is placed in a pipe carrying the fluid whose flow rate is to be measured a pressure drop occurs between the entrance and throat of the venturi meter. Parshall of the US. The working principle of Orifice Meter is the same like that of Venturi meter The orifice plate is being fixed at a section of the pipe creates an obstruction to the flow by providing an opening in the form of an orifice to the flow passage.

Measuring the rate of flow of liquid is essential many times and this simple device is widely used to do it precisely. Part IV - Miami-Dade Water and Sewer Department Standard Details. Raw exhaust gas flow meter is the equipment used to measure the flow rate of exhaust gas of the engine.

Named after its creator Dr. Soil Conservation Service the Parshall flume is a fixed hydraulic structure used in measuring volumetric flow rate in surface water wastewater treatment plant and. Chemical Engineering World is a leading online learning platform for get lot of updated knowledge about following streams.
