heat
This form of heat transfer occurs due to molecular vibration without bulk fluid motion.
What is conduction?
This property, defined as the change in the total Gibbs energy of a solution per mole of a component added at constant T, P, and composition of other components, is central to phase equilibrium calculations.
What is the partial molar Gibbs free energy (chemical potential)?
This minimum gas velocity needed to suspend solid particles and initiate fluidization is called this.
What is the minimum fluidization velocity?
Directed by Christopher Nolan, this 2010 film explores dreams within dreams.
What is Inception?
He proposed the model of the atom with electrons orbiting the nucleus, known as the planetary model.
Who is Niels Bohr?
The Stefan–Boltzmann law states that total emitted radiation is proportional to this power of absolute temperature.
What is the fourth power?
In electrolyte solutions, this extended form of Raoult’s Law accounts for ion–ion interactions by introducing a mean activity coefficient.
What is the Debye–Hückel equation?
This phenomenon happens when liquid droplets fall through perforations or gaps in trays instead of flowing across the tray, often caused by low vapor flow rates.
What is weeping?
This 1994 film features a slow-witted man recounting his life story while sitting on a bench, famously saying, “Life is like a box of chocolates.”
What is Forrest Gump?
This scientist’s work on electromagnetic waves confirmed Maxwell’s theories and led to the invention of radio.
Who is Heinrich Hertz?
This dimensionless number represents the ratio of thermal resistance to convective heat transfer and is critical in evaluating insulation effectiveness in heat exchanger design.
What is the Biot number?
In multicomponent mixtures, the fact that the sum of xi dlnγi over all components equals zero is a direct result of this fundamental thermodynamic equation.(DD)
What is the Gibbs–Duhem equation?
This effect describes the accumulation of solids or fouling materials on packing or trays, which reduces mass transfer efficiency and increases pressure drop.
What is fouling?
This iconic Indian film from 1957, directed by Guru Dutt, is famous for songs like "Waqt Ne Kiya Kya Haseen Sitam."
What is Pyaasa?
Awarded the Nobel Prize in Physics in 1983 for his theoretical studies on the structure and evolution of stars, this Indian-American astrophysicist is well known.
Who is Subrahmanyan Chandrasekhar?
In pool boiling, the point at which heat flux reaches its maximum before film boiling begins is called this.
What is the critical heat flux?
The Gibbs–Duhem equation implies that if one component’s activity coefficient increases with composition, the other component’s activity coefficient must change in this way.
What is decrease?
The pressure drop across a packed bed can be estimated using this empirical equation involving bed voidage, particle diameter, fluid velocity, and fluid viscosity.
What is the Ergun equation?
This director is known for his distinct style and made the 1994 film “Pulp Fiction.”
Who is Quentin Tarantino?
This mathematician laid the foundations of calculus independently of Newton and contributed to the theory of probabilities.
Who is Gottfried Wilhelm Leibniz?
In nucleate boiling, this empirical relation predicts heat flux as a function of excess temperature and fluid properties, and is often used before reaching the critical heat flux.
What is the Rohsenow correlation?
In regular solution theory, this dimensionless parameter quantifies deviations from Raoult’s law and is related to the difference in cohesive energy densities of components.
What is the Flory–Huggins interaction parameter (χ)?
This type of structured packing uses corrugated metal sheets arranged at an angle to enhance surface area and improve mass transfer efficiency.
What is Mellapak (or structured packing)?
This 2001 film by Sanjay Leela Bhansali, starring Aishwarya Rai and Salman Khan, is known for its lavish sets and tragic love story.
What is Hum Dil De Chuke Sanam?
A pioneer in space science, he founded the Indian Space Research Organisation (ISRO) in 1969.
Who is Vikram Sarabhai?
