    1. The Planning fallacy. it is apparent time and again that project planners are always the most optimistic and do not have a sufficient contingency.

    2. The principle of heat transfer is a fundamental concept that is used in many aspects of building commissioning, including HVAC system commissioning. It helps to ensure that buildings are comfortable, energy-efficient, and safe.

  1. My favourite phenomenon is Joule-Thomson effect. Fluids experience a change (drop or rise depending on the gas) in temperature after going through an adiabatic drop in pressure. This is due to the conservation of enthalpy of the fluid throughout the process.
    I use it when I need to find out how much will CO2 gas drop in temperature as it goes through a pressure-reducing regulator. It’s common for regulators to form a layer of ice due to freezing vapor in the air resulting from the drastic drop in temperature as it gets in contact with the surface of the regulator.

  2. As a mechanical engineer, I have a deep appreciation for Bernoulli’s principle, which states that as fluid velocity increases, pressure decreases. This phenomenon has a variety of real-world applications, from airplane wings to fuel pumps. At work, I often use Bernoulli’s principle to design and optimize fluid systems. By manipulating the velocity of fluid through pipes or valves, I can control the pressure and flow rate, ensuring that the system operates efficiently and effectively.

  3. Black oxide: the process of coating ferrous materials, stainless steel, etc., increases the resistance of corrosion or abrasion.
