Pumps: centrifugal, positive displacement, axial flow. Compressors: reciprocating, rotary, centrifugal.
Centrifugal pumps use a rotating impeller to move fluid.
Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge.
Axial flow pumps use propellers to move fluid.
Reciprocating compressors use pistons to compress gas.
Rotary compressors use rotating screws or vanes to compress ...
Characteristic curve of a pump shows the relationship between flow rate and head developed by the pump.
It is a graph plotted between flow rate and head developed by the pump.
It helps in determining the efficiency of the pump.
The curve is obtained by conducting experiments on the pump.
It is used to select the appropriate pump for a given application.
Shutoff pressure is the maximum pressure a pump can generate when it is not pumping any fluid.
Shutoff pressure is also known as deadhead pressure.
It is the pressure at which the pump can no longer move any fluid.
It is important to know the shutoff pressure to prevent damage to the pump and system.
For example, if the shutoff pressure of a pump is 100 psi, the pump will stop generating flow when the pressure in the syste
Types of columns and their selection criteria for engineering projects.
Types of columns include steel, concrete, timber, and composite columns.
Selection criteria depend on factors such as load capacity, material availability, and cost.
For example, steel columns are often used in high-rise buildings due to their strength and durability.
Concrete columns are preferred for their fire resistance and low maintenance.
Timber c...
Design of column, heat exchanger, and centrifugal pump involves various factors such as fluid properties, operating conditions, and material selection.
Column design involves determining the column diameter, height, and packing material based on the required separation efficiency and pressure drop.
Heat exchanger design involves selecting the appropriate type of exchanger, determining the heat transfer area, and selectin...
Joule-Thomson coefficient is the change in temperature of a gas when it is allowed to expand or contract without any work being done.
It is a measure of the rate of change of temperature with respect to pressure at constant enthalpy.
It is used in cryogenic technology to determine the cooling effect of a gas when it expands through a valve or porous plug.
The coefficient can be positive or negative depending on the gas an...
Refrigeration cycle is a thermodynamic process used in refrigerators and air conditioners to transfer heat from a low-temperature region to a high-temperature region.
The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.
The refrigerant is compressed by the compressor and then condensed in the condenser, releasing heat to the surroundings.
The high-pressure liquid refrigerant ...

Domain based questions and basic aptitude question
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

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
