Fire NOC conditions refer to the requirements set by the fire department for ensuring fire safety in a building or establishment.

• Fire NOC is required before starting any construction or occupancy of a building.

• The building must comply with fire safety regulations such as having fire extinguishers, smoke detectors, and fire alarms installed.

• Regular fire drills and training for occupants are necessary to ensure preparedn...read more

25 KV AC is more efficient for railways due to lower energy losses over long distances.

• 25 KV AC is more efficient for long distance transmission as it experiences lower energy losses compared to 750V DC.

• 25 KV AC allows for higher speeds and heavier loads on the railway system.

• 25 KV AC is the standard voltage used in many modern railway systems around the world, such as in Europe and parts of Asia.

• 750V DC may be more su...read more

Reverse a string without using string or inbuilt function

• Create an array of characters to store the string

• Use two pointers, one at the beginning and one at the end, swap characters until they meet

• Repeat until all characters are swapped

SFD stands for Shear Force Diagram and BMD stands for Bending Moment Diagram in structural analysis.

• SFD shows the variation of shear force along the length of a beam or structure.

• BMD shows the variation of bending moment along the length of a beam or structure.

• Both diagrams are essential for analyzing the internal forces in a structure.

• They are commonly used in civil and mechanical engineering for designing and analyzi...read more

Thrust forces for beams can be calculated using equations of equilibrium and considering external loads.

• Calculate the sum of all external forces acting on the beam.

• Determine the direction of the forces (compression or tension) based on the beam's support conditions.

• Apply equations of equilibrium to calculate the thrust forces at different points along the beam.

• Consider any distributed loads or moments that may affect t...read more

Gpm for water supply pump can be calculated by dividing the flow rate in gallons by the time in minutes.

• Calculate the flow rate in gallons per minute (GPM)

• Determine the time in minutes over which the flow rate is measured

• Divide the flow rate by the time to get the GPM value

Heat exchangers are devices used to transfer heat between two or more fluids, ensuring efficient heat transfer and temperature control.

• Transfer heat between fluids

• Maintain temperature control

• Increase energy efficiency

• Commonly used in HVAC systems, refrigeration units, and chemical processing plants

Alignment methods are techniques used to ensure proper positioning and orientation of mechanical components.

• Common alignment methods include laser alignment, dial indicator alignment, and straight edge alignment.

• Laser alignment uses a laser beam to measure and adjust the alignment of components.

• Dial indicator alignment uses a dial gauge to measure the alignment of components.

• Straight edge alignment involves using a str...read more
