The weight of 16 mm dia steel of 1 m length is 1.58 kg.

• The weight of steel can be calculated using the formula: weight = (d^2/162) * L, where d is the diameter in mm and L is the length in meters.

• Substituting the values, we get weight = (16^2/162) * 1 = 1.58 kg.

• This weight is for mild steel. The weight may vary for other types of steel.

• The weight of steel is an important factor in construction and design calculations.

M-20 grade concrete weighs approximately 2400 kg per cubic meter.

• M-20 grade concrete is a commonly used grade of concrete in construction.

• The weight of M-20 grade concrete is determined by the density of its components.

• The components of M-20 grade concrete include cement, sand, and coarse aggregates.

• The weight of each component and their proportions determine the overall weight of 1 cubic meter of M-20 grade concrete.

Concrete slump is the measure of consistency and workability of concrete.

• Slump test is conducted to determine the consistency of freshly mixed concrete.

• The minimum slump for concrete used in road construction is 25-50 mm.

• The maximum slump for concrete used in heavily reinforced structures is 100-150 mm.

• The slump value can be adjusted by adding water or admixtures to the concrete mix.

• A higher slump value indicates a mor

A WTP flow diagram shows the process of water treatment and purification.

• The flow diagram typically includes structures such as screens, sedimentation tanks, filters, and disinfection units.

• Screens remove large debris and particles from the water.

• Sedimentation tanks allow suspended particles to settle to the bottom.

• Filters remove smaller particles and impurities.

• Disinfection units use chemicals or UV light to kill bact...read more
