What is critical speed of pump?
Critical velocity is the speed that a falling object reaches when gravity and air resistance equalize on the object.when a liquid posses streamlined motion and its velocity is less than certain limiting velocity is called critical velocity for fluids and critical velocity for satellites can be defined as the velocity will give stable orbit, this is called the critical velocity for satellites

Critical speed means where natural frequency is equal to system frequency.
Is vlsi design a theory or derivation subject?
VLSI is combined of both theory and derivation with more diagrams
What is torsional critical speed?
The term torsional critical speed of centrifugal pumps and associated drive equipment refers to the speed of a pump rotor or related rotating system that corresponds to a resonant frequency of torsional vibration of the rotating system. Torsional critical speeds are associated with torsional or angular deflection of the rotor and are not to be confused with lateral critical speeds associated with lateral deflection. The two are separate entities. A given rotor or rotating system may possess more than one torsional resonant frequency or torsional critical speed. The lowest frequency which produces the "first mode shape" and "first torsional critical speed" is in general of the most concern. Torsional vibration is caused by torsional excitation from sources such as variable frequency drive motor toque pulsations, combustion engine torque spikes and impeller vane pass pulsation. The calculation of the first torsional critical speed is fairly simple for simple rotor systems.
Derivation of critical speed of grinding mill?
The critical speed of a grinding mill is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inner surface, leading to no ball fall and higher efficiency. It is calculated by using the formula: critical speed = 42.3/sqrt(D-d), where D is the diameter of the mill in meters and d is the diameter of the grinding media in meters.
What are some examples of real life hyperbola?
The orbit of objects that approach the Sun, or Earth, from far away, above a certain critical speed.At a certain critical speed, the orbit will be a parabola. Above the critical speed, the orbit will be a hyperbola. (In both cases, the object will go away, never to come back.) Below the critical speed, the orbit is an elipse or a circle.The orbit of objects that approach the Sun, or Earth, from far away, above a certain critical speed.At a certain critical speed, the orbit will be a parabola.

What is the derivation of the speed of sound in a medium?
The speed of sound in a medium is derived from the properties of the medium, such as its density and elasticity. It is calculated using the formula: speed of sound square root of (elasticity / density).
How the critical speed of ball mill is determined?
The critical speed of a ball mill is determined by the rotation speed of the mill and the diameter of the grinding media. It is calculated using the formula: critical speed = 42.3/sqrt(d), where d is the diameter of the mill in meters. Operating above the critical speed can lead to cascading and ineffective grinding, while operating below can lead to cataracting and unproductive milling.
What is critical speed of a SAG mill?
The critical speed of a SAG mill is the speed in RPM's at which centrifugal force causes the material being ground to be held against the inside of the shell. This speed is only dependent on the diameter of the mill.

What does it mean by critical speed of a compressor?
The critical speed of a compressor refers to the rotational speed at which the natural frequency of the compressor rotor coincides with one of its bending modes. When the compressor operates near or at the critical speed, it can experience significant vibrations and potentially fail due to resonance effects. Engineering designs are typically aim to avoid operating at critical speeds to ensure the compressor's stability and reliability.

What is critical speed of steam turbin?
Answer:Turbine shaft material has its own natural frequency, when turbine rotates on such a speed that frequency of shaft become close to its natural frequency, machine causes noise & high vibrations because of resonance due to matching of frequency. Running of Steam "TURBINE" on this speed is avoided & this is called Critical speed. A turbine may have more then one critical speed, which may depend upon number of couplings.A second critical speed is when the Turbine blade tips approach the speed of sound. This effectively limits the speed of a turbine and explains why power plants tend to have turbines of the same capacity.Critical speed of the turbine is the rotor speed at which natural frequency of the assembled rotor (rotor shaft with discs, blades, shrouding strips etc in assembled condition) becomes equal to the operating speed. This is usually a expressed as a range (critical speed range).There are multiple critical speeds. However, the operating speed of the turbine may be above or below the first / lowest critical speed. Accordingly it is called as a flexible or a rigid rotor.Venkatesh
