A collision could occur when the distance decreases and bearing between two vessels do what?
A collision could occur when the distance between two vessels decreases and the bearing remains constant. This indicates that the vessels are on a collision course. Vigilance and timely action to change course or speed are critical to avoid a collision.
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 derivation of critical speed?
Critical speed is the speed in RPM at which a rotating machine will destroy itself by all harmonic vibrations coinciding at maximum vibration.
State A machinery that should be allowed to operate to a critical speed?
State A machinery that should be allowed to operate to a critical speed?
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.
How fast is the speed of blood inside the vessels?
it depends upon the size of blood vessels,some are small in size and some are big,in this situation there is alteration of blood flow,so the speed of blood inside the vessels wont be constant
Was the titanic top speed?
The top speed for the Olympic-Class vessels was probably about 23 knots.
What is the speed limit for vessels near docks?
A speed not fast enough to produce a noticeable wake.
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 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
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
