Q1. What is mean by shear key
Ans. 
Shear key is a device used to transfer shear forces between two components in a structure.
• Shear keys are typically used in construction joints to prevent sliding between adjacent components.

• They are designed to resist horizontal forces and ensure stability.

• Shear keys can be found in structures such as bridges, buildings, and dams.

• Examples include shear keys in bridge expansion joints to prevent movement between bridge

Q2. Different between columns and beams
Ans. 
Columns are vertical structural members that support loads, while beams are horizontal members that transfer loads to columns or walls.
• Columns are vertical and primarily support compressive loads.

• Beams are horizontal and primarily support bending loads.

• Columns are typically taller than they are wide, while beams are typically wider than they are tall.

• Examples: In a building, columns support the weight of the floors abo...read more

Q1. Bending moment of beam
Ans. 
Bending moment of a beam is a measure of the internal bending stresses within the beam.
• Bending moment is the algebraic sum of moments about the neutral axis of the beam.

• It is calculated by multiplying the force applied to the beam by the perpendicular distance from the force to the point of interest.

• Bending moment can be positive (causing tension) or negative (causing compression) depending on the direction of the forc

Q2. Shear force of beam
Ans. 
Shear force of a beam refers to the internal force that causes a portion of the beam to slide in relation to an adjacent part.
• Shear force is perpendicular to the axis of the beam.

• It is caused by external loads applied parallel to the cross-section of the beam.

• Shear force can cause bending or deformation in the beam.

• Calculating shear force involves analyzing the forces acting on the beam and determining the internal for

Q2. What is npsh available
Ans. 
NPSH available stands for Net Positive Suction Head available, which is a measure of the absolute pressure at the suction port of a pump.
• NPSH available is the total suction head in feet absolute at the suction nozzle of the pump.

• It is important for ensuring that the pump does not cavitate, which can cause damage to the pump and decrease efficiency.

• NPSH available is calculated by subtracting the vapor pressure of the li...read more

Q3. How to calculate NPSH
Ans. 
NPSH is calculated by subtracting the vapor pressure of the liquid from the total head of the pump.
• NPSH = H - (Pv / rho * g)

• H is the total head of the pump

• Pv is the vapor pressure of the liquid

• rho is the density of the liquid

• g is the acceleration due to gravity

• Ensure all units are consistent (e.g. meters, Pascal, kg/m^3, m/s^2)

Q4. Draw two phase system p&ID
Ans. 
A two-phase system P&ID shows the process flow of a system with two distinct phases.
• Identify the two phases involved in the system (e.g. liquid-gas, solid-liquid).

• Use different symbols to represent each phase on the P&ID.

• Show the flow direction and connections between components in the system.

• Include labels and legends to explain the components and their functions.

• Ensure clarity and consistency in the representation of
