Engineering AllOther (1379) Can a 50-Hz designed transformer be used at 60-Hz system? Is the same remains true, when a 60-Hz designed transformer be used at 50-Hz system? Consider only frequency variation. The voltage remains as rated value in all cases. Justify the answer.
2 7982we have many gas turbine blades, during the shot blasting process some of shots entrapeed in the cooling hole of blades..how can we remove the shots entrapped in holes????
1 4077Hello, im taking an introduction to PLC..and i'm having a hard time on creating a program for 2 lamps blinking alternately with this button characteristics: 1.) One push button (starts upon pressing) 2.) Same push button (when pressed again, will pause the system) 3.) Same push button (when pressed again, will continue the paused system) 4.) Same push button (when pressed within 2 seconds, will shut off the system) Pls..i know this is just a simple problem for you guys..

1 4264Can a transformer designed for a particular voltage and frequency rating be used for different set of mentioned ratings? Assume that the winding does not get burnt because of overheating at higher voltage. If yes, then under which constraint it is possible?
1 3239How can we say that accuracy of measurement increases by using 3 or 4 wire RTD? because for example: If resistance of RTD element is say r ohms and Resistance of the cable from transmitter to RTD is R ohms And if 4 wire RTD is used, ____._____________________ R ohms | |_____._____________________ R ohms / \ / r ohms \ \ | |______.__________________ R Ohms | |_______._________________ R ohms Then the actual resistance measured will be: Total = r + R/2 + R/2 = r +R Ohms Note: r+R instead of r ohms. hence error
