Gharda Chemicals Limited Senior Instrumentation Executive Interview Questions and Answers

Designing a heat exchanger involves determining heat transfer requirements, selecting appropriate materials, and optimizing the design for efficiency.

• Determine heat transfer requirements based on the fluids involved, flow rates, and temperature differentials.

• Select appropriate materials based on the compatibility with the fluids, operating temperatures, and pressure requirements.

• Optimize the design for efficiency by co...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 and is expressed in units of energy (such as Joules or calories).

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

• Enthalpy change (ΔH) is commonly...read more
