Q1. What is tip speed, and how do you calculate it from the laboratory to the pilot plant?
Ans. 
Tip speed is the speed at the outer edge of a rotating object, calculated by multiplying the radius by the angular velocity.
• Tip speed is the speed at the outer edge of a rotating object.

• It is calculated by multiplying the radius of the object by the angular velocity.

• In the laboratory, tip speed can be calculated using the formula: Tip Speed = 2 * π * Radius * RPM.

• In the pilot plant, the same formula can be used to calc...read more

Q5. How do the P/V ratio and tip speed affect the selection of scale-up, and what criteria do you use for this selection?
Ans. 
P/V ratio and tip speed impact scale-up selection in process engineering.
• P/V ratio affects the level of shear stress in the system, influencing mixing and reaction rates.

• Higher tip speeds can lead to increased shear forces and heat generation, impacting product quality.

• Selection criteria include desired mixing intensity, heat transfer requirements, and shear sensitivity of the product.

• For example, in pharmaceutical man...read more
