TURTLE TURBINES Interview Questions, Process, and Tips

Entropy is a measure of disorder or randomness in a system.

• Entropy is a thermodynamic quantity that describes the amount of energy in a physical system that is not available to do work.

• It is a measure of the number of possible arrangements of particles in a system.

• Entropy tends to increase in closed systems over time, leading to a state of maximum disorder or equilibrium.

• An example of entropy is the melting of ice into...read more

Enthalpy is a thermodynamic property that represents the total energy of a system, including internal energy and the amount of energy required to create or release the system.

• Enthalpy is denoted by the symbol H in equations.

• It is defined as H = U + PV, where U is the internal energy, P is the pressure, and V is the volume.

• Enthalpy change (ΔH) is often used in chemical reactions to determine the amount of heat absorbed ...read more

The Bernoulli principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.

• States that as the speed of a fluid increases, its pressure decreases

• Used to explain lift in airplane wings - faster air above the wing creates lower pressure, lifting the wing

• Applies to various fluid dynamics situations such as pipe flow and blood flow

Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.

• Thermodynamics studies the transfer of energy in the form of heat and work.

• It involves concepts such as temperature, pressure, and entropy.

• The laws of thermodynamics govern the behavior of energy in systems.

• Examples include engines, refrigerators, and chemical reactions.

A thermodynamic cycle is a series of processes that involve the transfer of heat and work to and from a system.

• Involves a series of processes that form a closed loop

• Transfer of heat and work occurs during each process

• Common examples include the Carnot cycle, Rankine cycle, and Brayton cycle

Stress strain is the relationship between the force applied to a material and the resulting deformation, while tensile stress is the force per unit area applied to a material.

• Stress strain is a measure of how a material deforms under load.

• Tensile stress is the force applied to a material per unit area.

• Stress strain curve shows the relationship between stress and strain for a material.

• Tensile stress is calculated by div...read more

CAPA stands for Corrective and Preventive Actions. It is a systematic approach to identify and address root causes of problems to prevent recurrence.

• CAPA is a key component of quality management systems in manufacturing.

• Corrective actions are taken to address existing issues, while preventive actions are taken to prevent future issues.

• Example: Implementing a new training program for employees to prevent errors in produ...read more
