Saurashtra Chemicals Interview Questions, Process, and Tips

Drawing a simply supported beam with uniform load distribution in strength of materials.

• Draw a straight line representing the beam.

• Mark the supports at both ends of the beam.

• Draw arrows representing the uniform load distribution on the beam.

• Calculate the reactions at the supports using equations of equilibrium.

• Draw the shear force and bending moment diagrams for the beam.

• Calculate the maximum shear force and bending mo...read more

Pressure and velocity compounding are methods used to increase the efficiency of steam turbines.

• Pressure compounding involves dividing the pressure drop across the turbine into smaller stages, each with its own set of moving blades.

• Velocity compounding involves dividing the steam flow into smaller streams, each flowing through a set of fixed blades.

• Both methods increase the efficiency of the turbine by reducing the amo...read more

Iron-iron carbide diagram is a graphical representation of the phases of iron and carbon at different temperatures and compositions.

• Also known as the Fe-C diagram

• Shows the transformation of iron from ferrite to austenite to pearlite

• Used to determine the microstructure and properties of steel

• Helps in designing heat treatment processes for steel

• Important tool for metallurgists and materials engineers

Normalizing, annealing, and hardening are heat treatment processes used to alter the properties of metals.

• Normalizing involves heating the metal to a temperature above its critical point and then cooling it in air. This process improves the strength and toughness of the metal.

• Annealing involves heating the metal to a specific temperature and then cooling it slowly. This process reduces the hardness and increases the du...read more

Efficiency of Rankine cycle formula.

• Efficiency = (Net work output / Heat input)

• Efficiency = (1 - T2/T1)

• T1 is the temperature of steam at the inlet of turbine

• T2 is the temperature of steam at the outlet of turbine

• Net work output = (P1 - P2) * (V2 - V1)

• Heat input = m * (h1 - h2)

• m is the mass flow rate of steam

• h1 is the enthalpy of steam at the inlet of turbine

• h2 is the enthalpy of steam at the outlet of turbine
