What is the maximum suction head for pumping water?
I think, that's refer from your system. If you manipulate the surface pressure of the water, you will get a big value of water suction head with higher surface pressure. CMIIW....
What are the pros and cons of a capillary tube in refrigeration?
Capillary tube is a very simple device and can be manufacture easily at low cost. The capillary tube can limit the maximum amount of refrigerant to be charged eliminating the need for a receiver in the refrigeration system. Another advantage is when the refrigeration plant is stopped, the pressure along the capillary tube and the entire system remains constant which means that if the compressor is restarted it does not need moreÊpower to overcome high pressure in the system. Hence, smaller compressors can be used instead of big, expensive ones. A disadvantage with capillary coil is that this system is non adjustable due to the fact that the control of the flow of pressure is dictated by the inside diameter of the tube.
How do you build a pressurized system?
How do you build a pressurized system for a container system?
What are non mechanical systems?
A system that is mom-mechanical, basically means it contains human operators. Some examples I already have are: school system, health care system, government system.
What is a hydraulic drive system?
A hydraulic drive system is a transmission system. This system uses hydraulic fluid that has been pressurized to make a machine work. Most of these systems utilize hydraulic cylinders.
How damping progressively reduces the amplitude oscillations?
When energy is lost from the oscillating system, the amplitude of oscillationdecreases. When that happens progressively, we say that the oscillation is"damped". "Damping" is a description of the decrease, not its cause.
Define the terms logging interval dedicated control system and Frequency of Sampling?
what do you mean by terms under damped, critical damped and over damped frequency of control system?
Damping progressively reduces the amplitude of oscillation?
Vibratory motion of ideal systems in the absence of any friction or resistance continues indefinitely under the action of a restoring force. Practically, in all systems, the force of friction slows down the motion, so the systems do not oscillate indefinitely. The friction reduces the mechanical energy of the system as time passes, and the motion is said to be DAMPED. This damping progressively reduces the AMPLITUDE of OSCILLATION.
Why damping is small in ballistic galvanometer?
to get critical damped system
Is a pogo stick a critically damped system?
No, a pogo stick is not a critically damped system. It typically exhibits underdamped behavior when bouncing, with oscillations that gradually decay over time due to damping effects. The damping in a pogo stick is usually not enough to make it critically damped.
What is amplitude in physical science?
Amplitude is the magnitude of change in the oscillating variable,with each oscillation,within an oscillating system.
What is exitation voltage?
The maximum amount of time for a script to execute was exceeded. You can change this limit by specifying a new value for the property Server.ScriptTimeout or by changing the value in the IIS administration tools.
What is the difference between generator over excitation versus under excitation when attached to the grid?
Over Excitation is a condition when the Excitation System is providing too much field current and as a result, the rotor of the generator will over heat. The Excitation System is equipped with an Over Excitation Limiter. This limiter acts to reduce the Excitation Current if this condition exists Underexcitation is a condition when the generator is not getting enough Excitation Current. If the generator does not get enough Excitation Current, it can be un-synchronized with the grid. We call this slipping a pole. If this occurs, the generator can be severely damaged.

What is a excitation variable?
A variable that causes change in the output of a system. In a RC circuit, for example, the input V is the excitation variable
Damping coefficient for viscous fluids?
The damping coefficient ς is a parameter which determines the behavior of the damped system
Is it possible to have damped oscillations when a system is at resonance?
Resonanceis aforcethat remains in a opposite position.It is also observed in physical media such as strings and columns of air. Any waves traveling along the medium will reflect back when they reach the end. It is possible to have damped oscillations when a system is at resonance.
What happens if excitation fails in parallel oprating generator?
when excitation fails,Reactive power will be supplied by the system to which the generator is connected and generator will work as induction generator and its speed will rise a little. generator which was in over excitation mode will work in underexcitation.but there is under excitation limit which should not be reached so we should detect loss of excitation and trip generator
