What is diaphragm used for a centrifugal compressor?
diaphrams are static ones containing guide blades...steam from suction end enters the suction diaphragm and get guided to impeller of centrifugal compressor..ntermediate diaphrams contains diffusers which changes pressure energy..these daphragms forms a part of inner casing.
What state of matter can be used in hydraulic systems?
State? Or phase? It would be a liquid phase. But its state is unknown since the state of a substance includes its pressure, temperature AND phase. Phase is a part of a state, but a state is not a phase.
Why over speed protection is required in electrical motors?
dangerous high speed operation will increase centrifugal force and destroy machines rotor part or loosening in windings
What is the advantage of gravity die casting over high pressure die casting?
The tooling for gravity casting costs less than pressure die casting but the part cost in pressure die casting is much less. see Sand Casting. Die Casting: In the high pressure, requires a die casting machine to inject molten liquid or semi-liquid metal to a higher rate of die-casting mold cavity filling and solidification under pressure, forming and casting methods obtained. Gravity Casting: Uses the gravity or weight of the metal to fill the cavity producing a metal part. It does not require the use of an expensive die casting machine. The tooling cost is lesser for gravity casting because of the lower pressures needed to produce parts.
Which part of a hydraulic system has more pressure?
Pump
What happens to the pressure in all parts of a confined fluid if the pressure in one part is increased?
The Temperature increases. The Volume may decreased. The conditions are defined by Combined Gas Law.
Why cavitation will occur in Centrifugal Pumps and not in displacement pumps?
Cavitation occurs when the pressure on a liquid drops below the vapor pressure for the liquid or when gas is otherwise introduced to a pump such that it disrupts the flow of the liquid through the pump.Positive displacement pumps trap a quantity of liquid (or gas) and then increase the pressure by pushing (displacing) it into the discharge pipe. External pressure pushes the liquid into the pump chamber which then is made smaller before the pump chamber discharges its contents. If any gas enters the pump chamber along with a liquid it is simply compressed along with the liquid. Positive displacement pumps work just fine with both gases and liquids - although when gases are being compressed it is usually necessary to cool the pump chamber which heats up quite a bit during the almost adiabatic compression step of the pump. Cavitation does not occur in part because the pressure in the pump chamber is almost completely uniform. If the compression chamber drops below the vapor pressure of a liquid being pushed into it, the external pressure will continue to push the liquid in, then when the pump begins to decrease the volume, the valve allowing the liquid to enter will close and the volume of the contents is decreased until the pressure rises back above the vapor pressure of the liquid and it condenses in the pump chamber.A centrifugal pump uses a rotating impeller to increase the pressure and flow rate of a fluid. In centrifugal pumps, pressure is added by increasing the kinetic energy of the liquid and then, in essence, "throwing" the liquid into the discharge pipe where the higher kinetic energy liquid pushes on the liquid ahead of it to increase pressure. As the impeller moves through the liquid being pumped, it pushes on the liquid ahead of it, imparting additional kinetic energy to it. The liquid behind the impeller, however, actually experiences a little bit of a drop in pressure as the impeller tries to move away from it. Because liquids are fairly incompressible, this usually does not create any problem and the internal pressure of the liquid is sufficient to keep it in contact with the backside of the impeller. If the drop in pressure is low enough that the pressure drops below the vapor pressure of the liquid at the temperature present in the pump, the liquid will begin to vaporize. Once gas is present in the pump, it begins to cavitate - the liquid separates from the back of the impeller - especially near the tips. For this reason, introducing air or other gas into the liquid can cause cavitation, even if the pressure never drops below the vapor pressure of the liquid being pumped. This is also why centrifugal pumps are usually "primed" prior to being started up - to get all, or at least most, of the gas out of the line so that the pump won't cavitate.
Why is the pressure on each part of a horizontal line in a liquid the same?
because it is.
Increases actions regulated by the nervous system such as heart rate and blood pressure?
The baroreceptor is part of the autonomic nervous system. It increases actions regulated by the nervous system, such as heart rate and blood pressure.
What is diaphragm used for a centrifugal compressor?
diaphrams are static ones containing guide blades...steam from suction end enters the suction diaphragm and get guided to impeller of centrifugal compressor..ntermediate diaphrams contains diffusers which changes pressure energy..these daphragms forms a part of inner casing.
Does pressure rise when heat rises?
Heat and temperature are two different terms. Heat is the cause and temperature is the effect. So when the temperature increases then the pressure increases provided the volume remains constant. This is what we call part of Charle's law.
What part of the refrigeration system changes the high pressure side to the low pressure side?
The compressor changes the low pressure gas into a high pressure gas which then has the heat of compression removed in the condensor to turn it into a high pressure liquid.
How does the ocean changes as you go deeper?
As depth increases temperature drops, water pressure increases and the eyes of sea creatures become more primitive. Electroluminescence plays a greater part in identification.
How does a straw work?
As you create a partial vacuum in the top part of the straw, the weight of the entire atmosphere above the glass applies a pressure of 15 PSI on the liquid surface. This pressure pushes the liquid up the straw until the pressure in the straw returns to 15 PSI too. If you keep creating the partial vacuum the air pressure will push the liquid all the way to the top of the straw and out.
How does decreasing the gas volume affected the pressure of a gas?
When other variables are held constant in ideal gas law, volume and pressure have an inversely proportional relationship, which means that as volume increases, pressure decreases and as volume decreases, pressure increases. Look at desmos and put in y=1/x and look at the positive part of the graph to get a better idea of what I'm talking about.
What will happen to the ability of a gas to dissolve in a liquid if the temperature increases?
Yes, that is part of the problem with global warming, if the temperature of the oceans increases, they will release more carbon dioxide in the form of gas because it will be less soluble in the warmer water. Open a cold soda and a warm soda, which has more gas come out?
What is the effect of pressure in the solubility of gas in liquid?
The higher the pressure, the more atomic collisions will take place, reducing the speed at which atoms can diffuse. Alternatively, the higher the pressure(Pressure=Force/Area), the higher the force is that is acting on the diffusing material, decreasing the diffusing materials ability to migrate to all regions of the liquid.
