What is critical pressure in nozzle?
Critical pressure in a nozzle is the pressure at which the flow of material through the nozzle reaches its maximum. Beyond which any increase in pressure will not result in an increase in flow. The point at which the velocity of a fluid in the throat of the nozzle reaches the local speed of sound, creating a sonic wave, or a sonic choke.
What is the function of the impeller in a centrifugal pump?
Impeller make the flow has velocity in a centrifugal pump. The purpose of pump is increasing the pressure. The flow has velocity envergy via impeller and the energy change to pressure energy in diffuser.
what is purpose of nozzle in steam turbine?
It sends hot gases from the combustion chamber to the 1st stage turbine blades at the correct angle and speed
Fluid mechanics in venturi meter?
Venturi Meter is a device used for measuring the flow of the fluid.
Why the centrifugal pump is called high discharge pump?
for a simple reason because it has high discharge than any other available pump. the centrifugal pump uses the centrifugal force to push out the fluid centrifugal force = (mass *velocity2)/radius. hence centrifugal force is directly proportional to the square of the velocity, in this case being the velocity of the fluid. power provided to pump proportional to the force exerted by the impeller.hence higher the power results in higher centrifugal force implying square of the velocity of the fluid. higher the velocity of the fluid higher the discharge of the pump.
Difference between turbulent flow and streamlined flow?
Streamline flow:The flow of a fluid is said to be streamline (also known as steady flow or laminar flow), if every particle of the fluid follows exactly the path of its preceding particle and has the same velocity as that of its preceding particle when crossing a fixed point of reference.Turbulent flow:The flow of a fluid is said to be turbulent or disorderly, if its velocity is greater than its critical velocity. Critical velocity of a fluid is that velocity up to which the fluid flow is streamlined and above which its flow becomes turbulent. When the velocity of a fluid exceeds the critical velocity, the paths and velocities of the fluid particles begin to change continuously and haphazardly. The flow loses all its orderliness and is called turbulent flow.
What is critical velocity in fluid dynamics?
Critical velocity is that The Liquid Air flow in narrow pipe constatly.
What is critical velocity for 3 inch hose?
The critical velocity for a 3-inch hose depends on the fluid flowing through it. In general, critical velocity is the velocity at which the flow changes from laminar to turbulent. It can be calculated using the Reynolds number for the specific fluid and hose diameter.
How do you calculate flow velocity in a fluid system?
Flow velocity in a fluid system can be calculated by dividing the flow rate of the fluid by the cross-sectional area of the pipe or channel through which the fluid is flowing. The formula for calculating flow velocity is: Velocity Flow Rate / Cross-sectional Area.
What is critical flow in fluids?
Critical flow in fluids refers to the condition where the flow velocity in a fluid reaches the speed of sound. This is the point at which the flow transitions from subsonic to supersonic and is associated with significant changes in flow properties. Critical flow is important in various fluid dynamics applications, such as in nozzles and Venturi tubes.
What is the equation for fluid flow?
is the equation for flow velocity
How can I calculate the velocity of fluid flow in a pipe based on the pressure within the pipe?
To calculate the velocity of fluid flow in a pipe based on the pressure within the pipe, you can use the Bernoulli's equation, which relates pressure, velocity, and height of the fluid. By rearranging the equation and solving for velocity, you can determine the fluid flow velocity in the pipe.
What is the relationship between velocity gradient and fluid flow in a dynamic system?
The velocity gradient in a fluid flow system refers to the change in velocity across different points in the fluid. In a dynamic system, the velocity gradient is directly related to the fluid flow rate. A higher velocity gradient indicates a faster flow rate, while a lower velocity gradient indicates a slower flow rate. This relationship helps to understand how the fluid moves and behaves within the system.
How can one determine the flow velocity in a fluid system?
One can determine the flow velocity in a fluid system by measuring the rate of flow and the cross-sectional area of the system. By dividing the flow rate by the cross-sectional area, the flow velocity can be calculated.
What is convective acceleration and how does it impact fluid flow dynamics?
Convective acceleration is the increase in fluid velocity due to changes in flow direction. It impacts fluid flow dynamics by influencing the distribution of velocity and pressure within the fluid, leading to changes in flow patterns and turbulence.
Velocity of a fluid particle at centre of pipe is?
The velocity of a fluid particle at the center of a pipe in a fully developed flow is half of the maximum velocity in the pipe. This is known as the Hagen-Poiseuille flow profile for laminar flow.
What do you mean by critical velocity by method of dimensions establish its relation?
Critical velocity is the minimum velocity required for an object to overcome a particular resistance force. By using the method of dimensions, you can establish a relationship between critical velocity and the factors that influence it, such as the viscosity of the fluid, density of the fluid, and the size and shape of the object. By analyzing the dimensions of these factors and the force equation, you can derive an equation that relates critical velocity to these variables.
