10+ Ramco Systems Interview Questions and Answers

Density is the measure of mass per unit volume of a substance.

• Density is calculated by dividing the mass of a substance by its volume.

• It is usually measured in units of grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

• The density of a substance can be used to identify it, as different substances have different densities.

• For example, the density of water is 1 g/cm³, while the density of iron is 7.8 g/cm³.

• Density can also be affected by temperature and pr...read more

A pressure cooker is a kitchen appliance that cooks food quickly by trapping steam inside the pot.

• Water is added to the pot and heated to create steam

• The steam builds up pressure inside the pot, raising the boiling point of water

• This allows food to cook faster than traditional methods

• The pressure is released through a valve when cooking is complete

• Pressure cookers are commonly used for cooking rice, beans, and stews

Normality is the concentration of a solution expressed in equivalents per liter, while molarity is the concentration expressed in moles per liter.

• Normality measures the number of equivalents of a solute per liter of solution.

• Molarity measures the number of moles of a solute per liter of solution.

• Normality is used in acid-base reactions, while molarity is used in other types of reactions.

• For example, a 1M solution of HCl has a normality of 1N, while a 1M solution of NaOH has a...read more

Relative density is the ratio of the density of a substance to the density of a reference substance.

• It is also known as specific gravity.

• It is a dimensionless quantity.

• It is used to compare the density of different substances.

• Water is often used as the reference substance with a relative density of 1.

• If the relative density is less than 1, the substance will float in water.

• If the relative density is greater than 1, the substance will sink in water.

Newton's 1st law states that an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an external force.

• Also known as the law of inertia

• Inertia is the tendency of an object to resist changes in its motion

• Examples include a book on a table, a ball rolling on a flat surface, and a car moving at a constant speed on a straight road

• This law is the basis for seat belts and airbags in cars

Thermodynamics is the study of heat and its relationship with other forms of energy.

• It deals with the transfer of heat and energy between systems

• It involves the study of thermodynamic properties such as temperature, pressure, and entropy

• It is used in the design and analysis of engines, refrigeration systems, and power plants

• Examples include the Carnot cycle, the ideal gas law, and the laws of thermodynamics

Heat exchangers transfer heat between two fluids without mixing them, while condensers convert vapor into liquid by removing heat.

• Heat exchangers transfer heat between two fluids without mixing them

• Condensers convert vapor into liquid by removing heat

• Heat exchangers are used in HVAC systems, refrigeration units, and chemical processing plants

• Condensers are commonly found in air conditioning units, distillation columns, and power plants

The formula of salt is NaCl.

• Salt is a compound made up of two elements, sodium (Na) and chlorine (Cl).

• The chemical formula for salt is NaCl.

• It is an ionic compound, meaning that it is made up of positively and negatively charged ions.

• Salt is commonly used as a seasoning and preservative in food.

• It is also used in various industrial processes, such as the production of chlorine and sodium hydroxide.

Heat exchanger design involves determining the size, shape, and materials of the exchanger to efficiently transfer heat between two fluids.

• Heat exchanger design involves selecting the appropriate type of exchanger (e.g. shell and tube, plate heat exchanger)

• Calculating the required heat transfer area based on the heat duty and heat transfer coefficients

• Selecting materials that can withstand the operating conditions and prevent corrosion

• Optimizing the flow patterns of the fluid...read more

The 3rd Law of thermodynamics states that the entropy of a perfect crystal at absolute zero is zero.

• The 3rd Law of thermodynamics states that as the temperature of a system approaches absolute zero, the entropy of the system also approaches zero.

• It is impossible to reach absolute zero in practice, but this law helps in understanding the behavior of systems at extremely low temperatures.

• This law is important in the study of phase transitions and the behavior of matter at very ...read more

I prioritize based on urgency, assess available information, consult with team if needed, and make a quick decision.

• Prioritize based on urgency of the situation

• Assess available information quickly

• Consult with team members if needed

• Make a quick decision based on the information gathered

Gas Chromatography is a technique used to separate and analyze volatile compounds in a mixture.

• Gas Chromatography separates compounds based on their volatility and affinity for the stationary phase.

• It involves the use of a carrier gas to carry the sample through a column packed with a stationary phase.

• The compounds in the sample interact differently with the stationary phase, leading to separation.

• The separated compounds are detected and quantified using a detector, such as a...read more

Distillation is a process used to separate components of a liquid mixture based on differences in boiling points. Valves include gate, globe, ball, and butterfly. Cooling towers include natural draft, mechanical draft, and crossflow.

• Distillation is a separation process that involves heating a liquid mixture to create vapor and then cooling the vapor to get the desired components.

• Types of valves used in industrial processes include gate valves, globe valves, ball valves, and b...read more

There are typically two closed loops in a distillation column - one for reflux and one for reboiler.

• One closed loop is for reflux, where a portion of the condensed liquid is returned to the column as reflux to improve separation efficiency.

• Another closed loop is for the reboiler, where heat is added to the bottom of the column to vaporize the liquid mixture.

• These closed loops help maintain the necessary temperature and composition gradients for effective separation.
