Explain using drawings what is reverse PID action w.r.t PID controllers.
How many times we can use Fresh bentonite ford wall execution? Would like to know the clear concept of recycling. After flushing can we use it for another time time for flushing? Or we have to use it for for excavation only?
As a water tank loses heat, the temperature drops by 2 K/min when a heater is on, the system gains temperature at 4 K/min. A two-position controller has a 0.5 min control lag and a neutral zone of ± 4% of the setpoint about a setpoint of 323 K. Plot the heater temperature versus time. Find the oscillation period
How can we calculate 8- storied Madrasha Building pile capacity by taking SPT value at site?
why we use copper earthing for neutral while for body GI.
why power factor is important?
boolean isBadBoy(boolean hasGirlFriend , boolean isMarried, int age , String middleName , String lastName , String[] brotherName);
can u describe the method used for protection of transmission line.
Why do we need Interview?
why impedance relay is used for medium transmission line protection
why they were using TRIAC instead relay in some controllers and what is the advantages.
why direct mounted pressure transmitters is always installed with DBB ( double bleed block) valve in process line or top of the tanks ?
we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
I have a small system with two motors that are running on 380 vac, 60 hz. These motors are expensive and I usally get them from Brazil. I am adding another motor to the system, but I want to purchase a 480 vac, 60 hz motor to use. It will be on a VFD that is rated fro 380 thru 480. Is this posible and will I have to use a larger motor and derate it?
Generation of voltage for each phase are same of a turbogenerator.Although the short circuit current flow when two phase of turbogenerator are shorted(where current can't flow without potential difference),why?
