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 is the process of thermal energy moving from one object or substance to another.
Heat transfer occurs through three main mechanisms: conduction, convection, and radiation.
Conduction is the transfer of heat through direct contact between objects or substances.
Convection is the transfer of heat through the movement of fluids or gases.
Radiation is the transfer of heat through electromagnetic waves.
Examples of...
Mass transfer is the movement of substances from one place to another due to a concentration gradient.
Mass transfer involves the transfer of mass or substances between phases, such as from a liquid to a gas or from a solid to a liquid.
It occurs due to differences in concentration, temperature, pressure, or other driving forces.
Examples of mass transfer include evaporation, condensation, absorption, distillation, and ex...

CSTR and PFR are types of reactors, pumps are used to move fluids, heat exchangers transfer heat between fluids.
CSTR (Continuous Stirred Tank Reactor) has a constant volume and operates under steady-state conditions.
PFR (Plug Flow Reactor) has a varying volume and operates under unsteady-state conditions.
Pumps are mechanical devices used to move fluids from one place to another, like centrifugal pumps or positive displ...
Cracking is a process in which complex hydrocarbon molecules are broken down into simpler molecules.
Cracking is a refining process used to convert large hydrocarbon molecules into smaller, more valuable ones.
It is done by breaking the carbon-carbon bonds in the molecules.
Examples include catalytic cracking and steam cracking.
Reforming is a process used in the petroleum industry to convert low-octane naphtha into high-octane gasoline.
Reforming involves rearranging the molecular structure of hydrocarbons to increase their octane rating.
It is typically done using a catalyst at high temperatures and pressures.
The process can also produce hydrogen gas as a byproduct.
Reforming is an important step in the production of gasoline and other fuels in...
The range of a cooling tower refers to the maximum distance at which it can effectively cool air, while the approach is the temperature difference between the cooled water and the entering air.
Range of a cooling tower is typically around 5-20 degrees Fahrenheit
Approach of a cooling tower is usually around 8-15 degrees Fahrenheit
The range and approach of a cooling tower can vary based on factors such as design, size, an

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...
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...
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...
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
