MR1048 Friction Loss In Pipe Apparatus Fluids Engineering Training Equipment Didactic Equipment

1. Equipment introduction

1.1 Overview

Pressure drop in a pipe is the loss of fluid pressure due to friction between fluid particles and conductor walls and obstructions in the pipe.
Pipe friction is one of the classic laboratory experiments and has always occupied a place in the practical teaching of fluid mechanics. The research results and underlying principles are important to aerospace, industrial and mechanical engineers alike.
Used to determine the coefficient of friction in pipes of various diameters and roughnesses, to study pressure losses in different types of valves and different fittings, and to compare different flow measurement methods.
General instructions
The device consists of six straight pipe sections made of different materials, with different diameters and roughness. Also included are various accessories for studying straight pipe losses, various types of valves (gate valves, ball valves, angle seat valves, etc.), pipe fittings (in-line filters, elbows, sudden widenings, contractions, etc.) and Measuring elements (venturi tube, pitot tube, orifice flow meter, etc.).
Some measuring elements, such as venturi tubes, pitot tubes, etc., are transparent to observe their function.
Different pipe sections, valves and pipe fittings include multiple pressure measuring points, with quick-connect devices to install pipes connected to corresponding pressure measuring devices.
With this setup, friction pressure losses can be studied over a wide range of Reynolds numbers, covering laminar, transitional and turbulent flow regimes. Two water piezometers allow the study of pressure losses in laminar flow scenarios. Two Bourdon pressure gauges capture the pressure loss in turbulent flow conditions. It also includes a flow meter that measures the flow rate and compares it with measurements from the venturi and pitot tubes.
This unit requires a water supply system.

1.2 Features

The main components include the meter and flow meter support structure.
A centrifugal pump draws water from a sump in the hydraulic bench (bring your own) and delivers it to the test tube. The flow meter installed in the pipe can be quickly and easily installed into the unit test area. These meters are available in a variety of different measuring principles and accuracy levels.
By using a water pressure gauge or two Bourdon-type pressure gauges, the pressure drop across each flow meter can be measured. Valves ensure rapid venting of all pressure gauge lines.
The water discharged from the flowmeter under test is collected in a volumetric tank (located within the hydraulic bench) where the flow rate can be absolutely determined. The tank is stepped to accommodate low or high flows and has a built-in wave baffle to reduce turbulence. A graduated level tube shows the water level. The water returns to the sump through the drain valve.
