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

A STAAD model for a fixed pole is a structural analysis and design model used to determine the stability and strength of a pole that is fixed in place.
In a STAAD model for a fixed pole, the pole is typically modeled as a vertical member with fixed supports at the base.
The model considers factors such as wind loads, dead loads, and any other relevant loads that may act on the pole.
The analysis helps in determining the s...

Gear ratio is the ratio of the number of teeth on the driving gear to the number of teeth on the driven gear.
Gear ratio determines the speed and torque relationship between two gears.
It is calculated by dividing the number of teeth on the driving gear by the number of teeth on the driven gear.
A gear ratio greater than 1 indicates a reduction in speed and an increase in torque, while a ratio less than 1 indicates an inc...

The K factor is a value used in sheet metal design to determine the amount of springback that occurs during bending.
The K factor is a ratio that relates the neutral axis to the material thickness.
It is used to calculate the bend allowance and bend deduction in sheet metal bending operations.
A higher K factor indicates more springback, while a lower K factor indicates less springback.
Different materials and bending proc...
Spring back effect is the tendency of a material to return to its original shape after being deformed.
Spring back effect occurs when a material is bent or stretched and then released, causing it to return to its original shape.
It is commonly observed in materials like metals and polymers.
The amount of spring back depends on the material's elasticity and the magnitude of the deformation.
Spring back can be a desirable or...
