I applied via Recruitment Consulltant and was interviewed in Sep 2023. There were 3 interview rounds.
Negative slip in reciprocating pump occurs when the pump runs faster than the synchronous speed of the motor.
Negative slip occurs when the pump runs faster than the synchronous speed of the motor.
This can happen if the pump is not properly matched to the motor or if there is a mechanical issue causing the pump to run faster.
Negative slip can lead to decreased efficiency and potential damage to the pump.
Theoretical discharge pump formula calculates the flow rate of a pump based on various parameters.
Theoretical discharge pump formula: Q = A * V
Q = flow rate (volume per unit time)
A = cross-sectional area of the pipe or pump outlet
V = velocity of the fluid
Example: If A = 0.5 m^2 and V = 2 m/s, then Q = 1 m^3/s
A filler gauge is a tool used to measure the gap between two objects.
Filler gauge is used to check the clearance or gap between two surfaces.
It consists of a set of blades of varying thickness that can be inserted between the surfaces to measure the gap.
Commonly used in automotive and engineering applications for setting clearances in engines and machinery.
The velocity of flow at the inlet of a Kaplan turbine is typically high due to the design of the turbine blades.
The velocity of flow at the inlet of a Kaplan turbine is usually between 3 to 10 m/s.
The high velocity at the inlet helps in maximizing the energy extraction efficiency of the turbine.
The design of the Kaplan turbine blades allows for efficient energy conversion from the flowing water to rotational motion.
w q m stands for weight flow rate in fluid mechanics.
w q m is a measure of the mass of fluid passing through a given point per unit time.
It is calculated by multiplying the mass flow rate by the acceleration due to gravity.
Common units for weight flow rate include kg/s or lb/s.
Theoretical discharge pump formula calculates the flow rate of a pump based on various parameters.
Theoretical discharge pump formula is Q = A * V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the fluid.
The formula can be modified for specific pump types and applications, taking into account factors like pump efficiency and head loss.
Calculating the theoretical discharge ...
Pump discharge flow rate can be calculated using the formula Q = A * V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the fluid.
Calculate the cross-sectional area of the pipe using the formula A = π * r^2, where r is the radius of the pipe.
Determine the velocity of the fluid by measuring the speed at which the fluid is flowing through the pipe.
Multiply the cross-sectional...
Kaplan turbines are used for low head because they are designed to operate efficiently in low head conditions.
Kaplan turbines have adjustable blades that allow for optimal performance in low head situations
They have a higher specific speed compared to other turbine types, making them suitable for low head applications
Examples of low head applications include run-of-river hydroelectric plants and irrigation systems
I applied via Company Website and was interviewed in Sep 2023. There was 1 interview round.
Stress is internal resistance to deformation, while pressure is force applied on a surface. A continuous beam is a beam supported at multiple points. Three equilibrium conditions are required to stabilize a body in space.
Stress is the internal resistance to deformation in a material, while pressure is the force applied on a surface.
A continuous beam is a structural element that is supported at multiple points along its...
Load is the total weight supported by a structure or component, while force is a push or pull acting on an object.
Load is the total weight that a structure or component is supporting, including the weight of the structure itself and any external forces acting on it.
Force is a vector quantity that represents a push or pull acting on an object, causing it to accelerate or deform.
Load is a static quantity, while force can...
Nusselt number represents convective heat transfer, Biot number represents ratio of internal resistance to external resistance. Conduction is heat transfer through a material.
Nusselt number is used to characterize convective heat transfer, while Biot number represents the ratio of internal resistance to external resistance in a material.
Conduction is the transfer of heat through a material without any movement of the m...
Flow is the movement of a substance from one point to another, while viscosity is the resistance of a fluid to flow.
Flow refers to the movement of a substance, such as a liquid or gas, from one point to another.
Viscosity is the measure of a fluid's resistance to flow. High viscosity fluids are thick and flow slowly, while low viscosity fluids are thin and flow quickly.
Flow and viscosity are important factors in various...
Mercury is used in barometers to measure atmospheric pressure because it is denser than water and provides a more accurate reading.
Mercury is denser than water, so it creates a larger change in height in response to atmospheric pressure changes
Mercury has a lower vapor pressure than water, making it more suitable for measuring atmospheric pressure accurately
Mercury does not wet the glass walls of the barometer tube, en
I applied via Campus Placement and was interviewed in Jan 2024. There was 1 interview round.
Joule-Thomson coefficient is a measure of the temperature change of a gas when it expands or is compressed without any external work being done.
The Joule-Thomson coefficient is defined as the rate of change of temperature with respect to pressure at constant enthalpy.
It is denoted by the symbol μ.
A positive Joule-Thomson coefficient indicates that the gas will cool upon expansion, while a negative coefficient indicates...
I was interviewed in May 2023.
Centroid and center of gravity are similar concepts, but differ in their applications and calculations.
Centroid is the geometric center of a shape, while center of gravity is the point where the total weight of an object is considered to act.
Centroid is used in statics and geometry, while center of gravity is used in physics and mechanics.
Centroid can be calculated using geometric properties, such as area or volume, wh...
