9. CAVITATION IN A CENTRIFUGAL PUMP (179 views)
By: sethkohler
Cavitation is NOT air in the pump. It is vapor in the pump. So where is the vapor coming from?

This all "boils" down to something relatively simple, the vapor is coming from a phase change (meaning liquid is flashing to a gas)of the liquid being pumped. This phase change is a result of the decrease in pressure below saturation pressure at the suction of the pump, then as the pressure increases back above saturation pressure at the impeller vanes, the vapor bubbles collapse.

Cavitation can quickly destroy pumps due to the energy release as the vapor bubbles collapse. So what are the main causes of it? Are there preventive measures to keep it from happening? How do I know if the pump which has cavitated is damaged to severely to use?

ForumsCoursesCombined CyclePurpose of Intercept Valve
12. PURPOSE OF INTERCEPT VALVE (536 views)
By: mikecoats
The term Intercept Valve sounds pretty cool....possibly bringing to mind a scene from "Top Gun". However, the purpose of the intercept valve has nothing to do with fighter aircraft.

The intercept valve facilities quick shutdown of a steam turbine on a turbine trip. During a trip, the main stop and control valves immediately go shut. This prevents HP steam from being admitted to the turbine. However, there is still a lot of steam left downstream of the HP turbine in piping as well as the IP and LP sections of the HRSG. The intercept is located downstream of the IP section of the HRSG and upstream of the IP section of the turbine. On a turbine trip, the intercept valve closes, preventing steam already in the system from entering the IP section of the turbine. If this valve were not there, steam would continue to enter the IP section of the turbine, and the rotor would continue to rotate until this steam has been exhausted.

By: mikecoats
With all the high voltage around an industrial electrician, it is easy to forget about the normal, everyday 120 volt AC power. DON'T!! Contact with 120 VAC kills more people every year than any of the other voltage levels. It only takes ,1 to ,2 amps to kill a person, and 120 VAC can easily generate this amperage thru the normal resistance of a person. People often overlook 120 VAC because it is all around us. Respect it.

ForumsCoursesFoundationIdeal Gas Law and Tom Brady
15. IDEAL GAS LAW AND TOM BRADY (213 views)
By: mikecoats
The ideal gas law is PV=NRT, where P is Absolute pressure, V is volume,T is absolute temperature, N is the number of moles of gas, and R is the universal gas constant. When solving a problem using this law, it is very important to use absolute pressure and temperature.

For example, if a ball is inflated to 12 PISG at a temperature of 72 degrees F, and then taken into an environment where the temperature is 40 degrees F, the expected pressure at 40 degrees F can be calculated using the ideal gas law.

Can anyone come up with an answer? Post here. I will supply the correct answer on August 15. Good luck.

To start you off we can assume that volume is constant, and the number of moles of gas is constant (we are not adding or removing gas).

17. TRIACS (194 views)
By: mikecoats
Remember that Triacs normally have small amount of leakage current. This is normal but must be accounted. When measuring the output of a device using an triac with a high impedance meter such as a fluke, a "phantom" voltage may be detected. This is due the leakage current being detected by the meter, resulting in a voltage reading. It is best to use a low impedance device (analog meter, wiggins, etc) to measure voltage output of a triac operated device.

ForumsCoursesInstrumentation and ControlsRule of thumb when calibrating a "dumb" transmitter
18. RULE OF THUMB WHEN CALIBRATING A "DUMB" TRANSMITTER (299 views)
By: mikecoats
The old analog transmitters (called "dumb" transmitters) use voltage divider networks in the span and zero adjustments. A good rule of thumb for these transmitters (IE: Rosemount 1151) is to set the zero at process variable lower range value, set the zero to 4 mA then apply process variable for the upper range value. Instead of setting the output to 20 mA, note the reading on the ammeter when the upper range value is applied. Take a quarter of the difference between 20 mA and this reading. Now set the final value to 20mA, +/- this value. For example if the output reading when upper range value is applied is 18 mA. The difference between 20 mA and 18 mA is 2 mA. 1/4 of this value is .5 mA. Set the span adjust to 20.5 mA (instead of 20mA). Check the zero. It will have moved above 4mA. Reduce reading to 4mA. Check the span. It should be reading 20mA, of very close to it. This works because any span adjustment affects and zero adjustment and vice versa. By adjusting the span a little bit high as calculated, when the zero has to lowered, it brings the span right in line.
