BASIC QUESTIONS ON NUMERICALS
Thermodynamics is the study of heat and its relationship with other forms of energy.
It deals with the transfer of heat and work between systems
It involves the study of properties like temperature, pressure, and volume
It is used in designing engines, refrigeration systems, and power plants
The laws of thermodynamics govern the behavior of energy in all physical systems
Casting is a process of pouring molten metal into a mold to obtain a desired shape. Forging is a process of shaping metal by applying pressure and heat.
Casting involves pouring molten metal into a mold and allowing it to cool and solidify.
Forging involves shaping metal by applying pressure and heat, typically with a hammer or press.
Casting is used to create complex shapes with intricate details, while forging is used t...

Heat transfer coefficient changes with baffle spacing in heat exchangers. Other important factors include fluid properties, flow rate, and surface roughness.
Heat transfer coefficient increases with decreasing baffle spacing
Fluid properties such as viscosity and thermal conductivity affect heat transfer
Higher flow rates can increase heat transfer coefficient
Surface roughness can affect heat transfer by creating turbulen
Viscosity Index of lube measures its resistance to change in viscosity with temperature.
Viscosity Index (VI) is an important property of lubricating oils.
It measures the oil's ability to maintain its viscosity under different temperature conditions.
Higher VI means the oil's viscosity changes less with temperature, indicating better performance.
VI is calculated using kinematic viscosity measurements at two different tem...
Different kinds of distillation include simple distillation, fractional distillation, steam distillation, and vacuum distillation.
Simple distillation is used to separate liquids with different boiling points.
Fractional distillation is used to separate liquids with similar boiling points.
Steam distillation is used to extract essential oils from plants.
Vacuum distillation is used to separate liquids with high boiling poi...

Gibbs free energy is called free energy because it is the energy available to do work at constant temperature and pressure.
Gibbs free energy is the maximum amount of work that can be obtained from a system at constant temperature and pressure.
It takes into account both the enthalpy and entropy of a system.
If the Gibbs free energy is negative, the reaction is spontaneous and can do work.
Examples include the combustion o...
Maxwell's equations describe the behavior of electromagnetic fields.
There are four equations: Gauss's law, Gauss's law for magnetism, Faraday's law, and Ampere's law with Maxwell's addition.
Together, these equations explain how electric and magnetic fields interact and propagate through space.
Maxwell's equations are fundamental to the study of electromagnetism and have many practical applications, such as in the design...
