The energy created by the pump is kinetic energy according the Bernoulli Equation. Lab Presentation: Performance characteristic of centrifugal pump. Just like the figure shows. As can be seen, the head is approximately constant at low discharge and then drops to zero at Q max. This indicates that the maximum pump head is at low flowrates ranging between 0 to 15 gpm.
The pump in the lab was never to be ran at 1750rpm and was expected to be ran at 1740rpm, however the higher speed was causing problems and the instructor provided the experimental data. The inside pipe diameter was determined using Appendix C in the lab manual on page 56. Version 42-0006-05-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. Etc and the type of pumps teikoku pump, centrifugal pump, screw pump, gear pump. Data was recorded at 100, 85, 70, 55, 40, 25, and 0% flowrates by adjusting the globe valve where the maximum 100% flowrate was obtained by fully opening valve. A basic circuit comprises of a cell or power supply.
It must be noted, at very large Reynolds numbers, the friction factor is independent of the Reynolds number. On the other hand, centrifugal pump volutes were studied fairly frequently during the 20th. Usually there are no more than three or four pumps operating in parallel. Curve B is the combined pump curve for two pumps operating at the same time in parallel and curve C represents the combined performance for the three pumps. Objective : To observe and investigate the cell structure under the light microscope. Work Order 1 Multi-Stage Vertical Centrifugal Pump.
Even, efficiency of pumps in series is higher than that in parallel. This website does not use any proprietary data. Due to corrosion in the pump, the power input required was expected in increase to overcome this loss, however since the data is for 1740 and 1750 and it is hard to accurately use the graph to determine if this is true. Signals from the sensors are sent to a computer via this interface device. Combining two pumps increases the performance of the pumping system.
It was truly delightful working with Alerion on the build of our boat. Solar Powered Heat Pump By + Introduction Since the 7th century B. The exercises may be performed in separate tests and these results may be combined into a single session without shutting down the equipment and produced a single spreadsheet and graphs. The transformation of energy results in an increase in internal energy and heat as a resultant effect. Q-H characteristic diagram of centrifugal pump and of pipeline Pump head, on the vertical axis, is the difference between system back pressure and the inlet pressure of the pump ΔP pump. It should be noted that pump pressure is expressed in terms of total. In an internal combustion process, electrical energy is converted from chemical energy to mechanical and heat energy.
In the pumping system, the kinetic energy is transformed into potential energy. The elevation head static head represents the potential energy of a fluid due to its elevation above a reference level. To obtain the identification of this unknown bacterium, several biochemical tests needed to be performed in order to prescribe the correct medication to treat and cure the symptoms. Part 3 — Centrifugal Pump Performance Due to Pump Speed Control a. Selection Of Centrifugal Pumping Equipment.
Centrifugal pumps due to the pressure decrease in the eye of the impeller. One or both surface usually has a spherical curve. There are two types of lenses, converging and diverging. You must observe and analyze these as part of the lab. Chemical formula, Chemical formulas, Chemistry 1455 Words 4 Pages Laszlo Vass, Ed.
The change in potential energy translates into a change of pressure in the fluid. The flow of water through the centrifugal pump is regulated by a flow control valve on the discharge side of the pump. Are reported in the following publications; Survey of Feed Pump. After completing this report we conclude that the experiment is a success, with all the objective set is achieve with flying colors. Apparatus: Metre rule with holes drilled at the 25cm, 50cm and 75cm mark, 50g masses 50mm long bolt with a diameter of approximately 5mm, retort stand, boss head and clamp, 0-10 N spring balance, electronic pan balance ,wire or string for suspending masses from the metre rule, two bulldog clips.
When we use data that are related to certain product, we use only data released by public relations departments and allowed for use. . Centrifugal pump, gear pump, Pelton wheel and Francis turbine. Literature reports and the internal survey of engineering staff and students. The maximum operating condition is at 90% pump speed, where the efficiency is 40% at 1.
This experience has had as its main objective the centrifugal pump test. The correct directions are marked on the handle. If you dont like it theres a bar strawberry dna extraction lab report just strawberry. Series operation allows that commercially available equipment can be used in a particular system because sometimes a single pump operation would result in a pump with an extremely high head and thus an equally high horsepower. This kinetic energy is transmitted to an impeller. Caffeine, Coffee, Embryo 700 Words 3 Pages lab reports becca Medina Biology Lab 1107 Lab Notebook The Scientific Method Problem: Will a male or female have a higher heart rate after participating in the physical activity of running up three floors of a building? Read all instructions in this manual before operating pump.
