There are several types of fire, including Class A, Class B, Class C, Class D, and Class K fires.

• Class A fires involve ordinary combustible materials like wood, paper, and cloth.

• Class B fires involve flammable liquids like gasoline, oil, and grease.

• Class C fires involve energized electrical equipment.

• Class D fires involve combustible metals like magnesium and titanium.

• Class K fires involve cooking oils and fats.

There are different types of fire extinguishers for different types of fires.

• The most common types of fire extinguishers are ABC, CO2, and water-based extinguishers.

• ABC extinguishers are suitable for fires involving ordinary combustibles, flammable liquids, and electrical equipment.

• CO2 extinguishers are effective for fires involving flammable liquids and electrical equipment.

• Water-based extinguishers are used for fires...read more

The latest pump used in fire fighting systems is the centrifugal pump.

• Centrifugal pumps are commonly used in fire fighting systems due to their high flow rates and ability to handle large volumes of water.

• These pumps work by converting rotational energy from an electric motor into kinetic energy in the fluid, creating pressure to propel the water.

• They are designed to efficiently move water over long distances and deliv...read more

Different types of footings and their design

• Types of footings include spread footings, strip footings, and mat footings

• Spread footings are used for individual columns or walls

• Strip footings are used for a row of columns or walls

• Mat footings are used for large structures or where soil bearing capacity is low

• One-way footings distribute load in one direction, while two-way footings distribute load in two directions

• Design ...read more

Simply supported beam design involves determining the dimensions and reinforcement of a beam to support a given load.

• Calculate the maximum bending moment and shear force in the beam

• Determine the required dimensions of the beam based on the maximum bending moment and shear force

• Design the reinforcement, including the size and spacing of the bars

• Consider factors such as material properties, safety factors, and code requi...read more

The weight of steel per meter for a 25mm diameter

• The weight of steel per meter can be calculated using the formula: weight = (pi * diameter^2 * length) / 4

• The density of steel is approximately 7850 kg/m^3

• For a 25mm diameter steel rod, the weight per meter can be calculated as: weight = (3.14 * 0.025^2 * 1) * 7850 / 4 = 3.85 kg/m
