Paushak Instrument Executive Interview Questions and Answers

The question covers slope percentage calculation of kiln, tan value in oil analysis, and material and manpower handling.

• For slope percentage calculation of kiln, we need to measure the height and length of the kiln and use the formula tan(theta) = height/length.

• Tan value in oil analysis is used to determine the acidity of the oil. It is calculated by dividing the acid number by the saponification number.

Polymers in admixture formulations enhance performance, durability, and workability of construction materials.

• Polyvinyl Acetate (PVA): Improves adhesion and flexibility in cement-based products.

• Polyethylene Glycol (PEG): Acts as a plasticizer, enhancing workability and reducing water demand.

• Polyacrylate: Provides water retention and improves the flow characteristics of concrete.

• Styrene-Butadiene Rubber (SBR): Enhances ...read more

Current transformers are used to measure current in high voltage circuits. Transformers are protected using fuses, circuit breakers, and surge arresters. Voltage drop in cables is caused by resistance and can be calculated using Ohm's Law.

• Current transformers are used to step down current in high voltage circuits for measurement purposes.

• Transformers are protected using fuses to prevent overcurrent situations.

• Circuit b...read more
