I would like to know the best test procedure for to monitoring the centrifugal pump performance.?

i think u have to compare the theoretical head (in the graph included with pumps) with the real one

email mensa and take their test, that should be a quick gauge

Most Mfrs. of hard drives (i.e. Maxtor, Seagate, etc) have hard drive diagnostic programs available for their hard drives.\nDownload and run a diagnostic scan of your hard drive, their software will check for bad sectors. \nI always use the Mfrs. diagnostic software for hard drive issues - \nMaxtor uses Powermax - http://www.maxtor.com/portal/site/Maxtor/menuitem.3c67e325e0a6b1f6294198b091346068/?channelpath=%2Fen_us%2FSupport%2FSoftware+Downloads%2FView+By+Category%2FDesktop+Storage%2FDiamondMax+Family%2FDiagnostics&downloadID=22\nSeagate uses Sea Tools - http://www.seagate.com/support/seatools/index.html\nWestern Digital uses Data Lifeguard - \nhttp://support.wdc.com/download/

test the reactions of different substances in water. like um put in sugar and salt and then say it dissolved. And put in oil and say it freakin stayed seperate or whatever it does

Dear u should first tell your requirements which capacity of diesel genrator u r lookig for ?

do defragmentation, go to control panel and select performance and maintenance.

his applies only to transfer pumps since we deliberate add a gas load to the chamber and measure the quantity of gas issuing from the mechanical pump's exhaust. The method works as long as the gas chosen is not condensable, not captured in the foreline trap, does not dissolve in oil and is present in sufficient quantity to be measured.\n\nIf the mechanical pump has gas ballast, make sure it is off. Note the chamber's steady state pressure under the gas load. Put a bubble flow meter on the pump's exhaust, and measure the flow rate in cc per sec at atmospheric pressure. Using the gas in = gas out (at constant chamber pressure) principle, the gas entering must equal the measured throughput. If more precise numbers are needed, measure the exhaust gas temperature and the barometric pressure and re-calculate the quantity of gas at STP with Boyle's and Charles' law combined:\n\n(P1 x V1) / T1 = (P2 x V2) / T2\n\nExample The measured flow of gas at the pump's exhaust is 2.3 atm cc per minute from a chamber at a measured pressure of 1.4 x 10-5 torr. The exhaust gas temperature is 32°C and the barometric pressure is 750 mm Hg. What is the (corrected) effective pumping speed from the chamber?\n\n2.3 atm cc per min = (2.3/60) atm cc per sec\n= (2.3/60) x (760/1000) torr.liter per sec\n= (2.3/60)x (760/1000) torr.liter per sec at 750 torr and 32 °C\n= (2.3/60) x (760/1000) x (750/760) x (273/305) torr.liter per sec at STP\n= 0.0257 torr.liter per sec\nEffective pumping speed\n= (0.0257/1.4x10-5) liter per sec\n= 1838 liter per sec

Vibration is considered the best operating parameter to judge dynamic conditions such as :balance,  bbearing defects,  lubrication...... It is the perfect tool for trending overall vibration readings in process equipment such as : Rolling element bearing, Motors AC/DC, Pumps,\n Gearboxes, Compressors, Fans

There are various methods. the method to be used is selected as per the conditions. Following are the most common of them.\n\n1) Use of head type flow meters like orifice or venturi\n2) Use of annubar, pitot tube\n3) Use of ultrasonic/ UV transmitter reciever or doppler frequency shift system\n\nFor details, following books can be referred\n1) Instrument Engineer's handbook- Bela G Liptak\n2) Measurement Systems- E. O. Doeblin

I've worked with flowmeters for 20+ years and have never heard of this... what medium are you trying to measure?

i use to work in several water treament facilities. a flow meter is calibrated with the rising and lowering of the water level. the best flow meter utilizes a float inside a pipe that is slightly larger than the float.go to www.grainger.com. they have pictures of a few flow meters

Check this page\nhttp://www.evaluationengineering.com/archive/articles/1004/1004conformance_test.asp\n\nIt will give you the right info.

It may depend on the frequency or sampling rate that you want to achieve.  One possibility is to use an oscilloscope on a current sensing shunt or current sensing toroid.  This will give you a visual representation.\n\nIf you are looking for a peak current, you can use a digital multimeter with a peak hold feature, but keep in mind that you will be limited to the maximum response time of that meter.

Theres a tool called a Handheld Anemometer, amazon has one inexpensive

A voltmeter and an ammeter will provide the input power. You will need some form of dynamometer to measure output power.\n\nOutput power divided by input power yields efficiency.

I would try John Crane Mechanical Seals. They usually can address any type of pump seal or packing question.
