ANS:C - Higbie

The Higbie penetration theory, formulated by George E. Higbie in 1935, is a fundamental model used to describe mass transfer in fluid systems, particularly in situations involving the diffusion of solute species across a stagnant or slowly moving fluid boundary layer adjacent to a solid surface. In the Higbie penetration theory, it is assumed that the concentration gradient at the surface of the solid is the driving force for mass transfer, and diffusion is the dominant mechanism governing the transport of the solute through the boundary layer. The theory provides a mathematical framework for calculating the rate of mass transfer across the boundary layer based on the concentration difference between the bulk fluid and the surface of the solid. The key assumptions of the Higbie penetration theory include:

1. Steady-state conditions: The concentration profile in the boundary layer does not change with time.
2. One-dimensional diffusion: Mass transfer occurs predominantly in the direction normal to the solid surface.
3. Negligible convective transport: The fluid flow in the boundary layer is assumed to be negligible compared to diffusion.
4. Constant diffusivity: The diffusivity of the solute in the fluid is assumed to be constant.

Bernoulli's equation for fluid flow is derived based on certain assumptions that simplify the analysis of fluid dynamics. Let's analyze each option: A. Fluid flow is frictionless & irrotational.

• Frictionless: This assumption implies that there is no viscous drag or energy loss due to friction between fluid layers.
• Irrotational: This assumption means that the fluid does not have any rotational motion about its center of mass. This simplifies the flow field to be described mainly by its velocity potential.

• This assumption states that the flow parameters (velocity, pressure, density) do not change with time at any point in the fluid.

• Uniform: This would imply that the flow velocity is constant at every point in the fluid, which is typically not assumed in Bernoulli's equation derivation.
• Turbulent: Turbulent flow involves chaotic, irregular fluctuations in velocity and pressure, which are not assumed in the derivation of Bernoulli's equation.

• If the fluid is compressible, its density can change due to pressure variations, which complicates the application of Bernoulli's equation, designed for incompressible flows.

• Incompressible flow assumes that the density of the fluid remains constant, simplifying the continuity equation and the application of Bernoulli's equation.

• A. Fluid flow is frictionless & irrotational. This assumption simplifies the energy conservation along streamlines.
• B. Fluid flow is steady. This ensures that the flow parameters remain constant with respect to time.
• E. Fluid is incompressible. This simplifies the continuity equation and is commonly assumed for incompressible flows.

A cane sugar factory having a sugar production rate of 10 tons/day will produce about 40 tons/day of bagasse (after consumption by the factory for heating, etc.). A cane sugar factory producing 10 tons/day of sugar will generate about 40 tons/day of bagasse for several reasons:

1. Byproduct of Sugar Production:

• Bagasse Composition: Bagasse is the fibrous residue remaining after the extraction of juice from sugarcane. For every ton of sugar produced, a significant amount of bagasse is generated.

2. Yield Ratio:

• Extraction Ratio: The typical yield from sugarcane processing is around 10-12% sugar, meaning that a substantial portion of the cane's biomass (approximately 40-50% of the total weight) is left as bagasse after juice extraction.

3. Energy Source:

• Utilization: Bagasse is often used as a biomass fuel for heating and energy generation within the factory, making it a crucial part of the sugar manufacturing process.

4. Efficiency of Processing:

• Efficient Extraction: The sugar extraction process is designed to maximize the sugar yield while leaving behind a large volume of bagasse, which can then be utilized for energy or sold as a byproduct.

Sucrose content in cane sugar may be around 70 percent. The sucrose content in cane sugar may be around 70 percent for several reasons:

1. Composition of Sugarcane:

• Primary Component: Sugarcane is primarily composed of sucrose, which is the main sugar extracted during processing. Typically, the sucrose content in mature sugarcane ranges from 10 to 15%, but the extracted sugar product can be concentrated to about 70%.

2. Refining Process:

• Purification and Concentration: During the sugar extraction and refining process, impurities and non-sugar components are removed, resulting in a high concentration of sucrose in the final product.

3. Yield from Processing:

• Extraction Efficiency: The processes involved in sugar extraction, including crushing, juicing, and purification, are designed to maximize the recovery of sucrose from the cane, leading to a concentrated product.

4. Standard for Commercial Sugar:

• Commercial Grade: The 70% sucrose content is typical for raw and refined cane sugar used in food production, making it suitable for various applications in the food industry.
