What is the difference of an axial flow and centrifugal compressor?
The centrifugal flow compressor has a single or two stage unit using an impeller. The axial flow compressor is a multi-stage unit using alternate rows of rotating (rotor) blades and stationary (stator) vanes.
The axial stress on a member which is subjected to a sudden load when compared to load applied gradually is?
The axial stress on a member subjected to a sudden load is generally higher than that for a load applied gradually. This is because sudden loads create a quick increase in stress, potentially leading to a higher chance of failure in the member compared to a gradual increase in load that allows for more time for the material to adjust.
What is difference between axial flow and centrifugal LVAD?
Axial flow LVADs have a propeller-like rotor that spins along the device's long axis to propel blood forward, while centrifugal flow LVADs use a rotating impeller to draw blood into the device and then expel it outward. Centrifugal flow LVADs are generally more compact and have fewer moving parts compared to axial flow LVADs.
When the helical compression spring is subjected to axial compressive force the type of induced in the spring wire is?
When a helical compression spring is subjected to axial compressive force, the type of stress induced in the spring wire is primarily compressive stress. This stress is caused by the load that the spring is supporting, leading to a reduction in the length of the spring along its axial direction.
Relation between impeller width and its speed?
Increasing impeller width typically results in increased flow capacity and efficiency at a given speed as it can accommodate more fluid. However, wider impellers may require higher speeds to maintain proper velocity and prevent recirculation effects. It is important to consider the trade-offs between impeller width, speed, and the specific requirements of the application to optimize performance.
What is the difference between axial load and radial load?
Axial load (or thrust load) is a force applied parallel to the longitudinal axis, whereas, a radial load is a force applied transverse to this longitudinal axis.
How do you convert torque into axial load?
Torque=.2*F*Bolt Maj. Dim. F=axial force
What is a direct axial load?
It is a load applied in the axis of the member perpendicular (normal) to the cross section.
Why spiral columns load capacity is more than tied column?
tied columns use the steel rebar in axial load they will carry more load per diameter spiral columns use concrete in axial load. spiral columns resist barreling better but carry less load the longer they are
How do you find axial load on shaft?
(pie*d2/4)*stress
Load capacity of w6x15.0 BEAM?
you need to specify the load. axial? bending? how it's supported. this question doesn't have enough detail.

What is the significance of specific speed?
Specific speed (Ns) is a non-dimensional design index used to classify pump impellers as to their type and proportions. It is defined as the speed in revolutions per minite at which a geometrically similar impeller would operate if it were of such a size as to deliver one gallon per minute against one foot of head. The formula used to determine specific speed is Where N = Speed of Pump in RPM Q = Capacity in gpm at the best efficiency point H = Head per stage in feet at the best efficiency point The specific speed determines the general shape or class of the impeller. As the specific speed increases, the ratio of the impeller outlet diameter, D2, to the inlet or eye diameter, Di, decreases. This ratio becomes 1.0 for a true axial flow impeller. Low specific speed - Radial flow Impeller. Medium specific speed - Mixed flow Impeller. High specific speed - Axial Flow Impeller.
What is difference Between Vessel Column?
Pressure vessel is designed to withstand circumferential load,known as Hoope Stess, but column takes the axial load.
Which bearing can withstand both thrust and radial?
The “load” is the force applied to a bearing. The “radial load” is the force applied perpendicular to the shaft. The “axial load” is the force applied in the same direction as the shaft. Deep groove ball bearings sustain both radial load and axial load coming from both directions at the same time.
What is the amount of axial stress on a member which is subjected to a sudden load when compared to load applied gradually?
The maximum stress induced in a body due to suddenly applied load is twice the stress induced when the same load is applied gradually
