Whether Avrami equation is followed by most of the solid-state phase transformations or not needs to be explained. Concept Introduction: At constant temperature, the determination of solid phase transformation is done by using the Avarmi equation. Generally, it is used to describe the rate of kinetic crystallization. This equation is also known as the JMAK equation as it was founded by Johnson-Mehl-Avrami-Kolmology. This equation was first found in the year 1937 by Kolmogorov. And the first paper was published by Melvin Avrami during the years 1939 and 1941 in the Journal of chemical equations.

Consider a hot automotive engine, which can beapproximated as a 0.5-m-high, 0.40-m-wide, and 0.8-m-long rectangular block. The bottom surface of the block isat a temperature of 100°C and has an emissivity of 0.95.The ambient air is at 20°C, and the road surface is at25°C. Determine the rate of heat transfer from the bottomsurface of the engine block by convection and radiationas the car travels at a velocity of 80 km/h. Assume theflow to be turbulent over the entire surface because of theconstant agitation of the engine block. a) Calculate convective heat transfer coefficient (h). b) Calculate the total heat transfer rate

3) A pilot-plant Podbielniak centrifugal extractor operating at 11,400 x g (this is G₁) is capable of processing 500 mL/min of filtered fermentation broth and 125 mL/min organic solvent, giving a recovery of 95%. The rotating cylinder inside the extractor has a diameter of 20 cm and is 2.5 cm wide. You need to scale up this extraction by using a larger Podbielniak extractor that has a diameter of 91 cm and width of 91 cm and delivers 2,300 x g (G2). What flow rates (in L/min) should be used in the larger extractor to achieve the same recovery efficiency?

7) You are tasked with separating two proteins by ion exchange chromatography on a 30 cm long column with an inner diameter of 2 cm. The resin has a diameter of 100 μm and a void fraction of 0.3, and your mobile phase flows through the column at a rate of Q = 5 cm³/min. The Van Deemter coefficients A, B, and C have been determined to be 0.0228 cm, 0.0036 cm²/min, and 0.00053 min, respectively, for both proteins. Protein A elutes from the column with an average retention time of 27 min and standard deviation of 0.8 min. Protein B elutes from the column. with an average retention time of 33.8 min and standard deviation of 1.0. a) How many theoretical plates does the column contain? b) What flow rate (Q) will give you the maximum resolution? c) What is the minimum height of a theoretical plate for the system?
