Question 1Question 1Gas-solid fluidised beds are usually modelled as a two-phase system, using the Eulerian Multiphase flow equations. (a) Outline the main physical processes involved (without the equations) in such a system and discuss which processes can be ignored when flow conditions are laminar. You may assume that gas is the continuous phase, and particles are the dispersed phase. [8 marks](b) Considering a gas-fluidised bed is made...

Instructions-Assignment needs to be coded in Python. 1. The liquid phase reaction A4  B is to be carried out isothermally in a continuous flow reactor.The entering molar flow rate is 5 mol/min, and the volumetric flow rate is 10 L/min. The reaction rate is given by —rA —— kCA where k —— 0.01 1/min. It is desired to consume 99% of A. Calculate the volume of the plug flow reactor and CSTR necessary for t...

Question: Overview Your assignment is to choose a medium sized organic molecule that pertains to a career of interest to you, to build the molecule with materials of your choice and to describe your molecule using scientific terminology and chemical principles. Your report must include a detailed chemical description of the molecule. Your report may be submitted in almost any form (written report, slide show, video, etc.) as long as it meets ...

ObjectivesTwo of the basic tenets of atomic theory: Lavoisier’s Law of Conservation of Mass and Proust’s Law of Definite Proportions are applied to chemical reactions involving metallic copper and a copper salt. The data obtained from the reactions can be used to determine the empirical formulas of the compounds and the amount of water in a hydrate. To dete...

SummaryIn this paper the respective authors have given a review on the possibilities of testing different cyclosporine formulations with an importance on different parameters which can improve  biocompability and stability of cyclosporine administration. They have chosen cyclosporine A (CsA) for their investigation. The compound CsA is an organic compound and has the formula C62H111N11O12. It is a cyclic polypeptide which has 11 amino aci...

ObjectivesOur main purpose is to create a formula card for a nutritional bar using almond hull pulp as the main ingredient. To do this, we must formulate a batch process for the nutritional bar, then translate to shift-based, continuous production at an industrial scale. Almond hulls may contain aflatoxins, and as such are not regarded as safe for human consumption yet; so we must derive a process for making almond hulls safe to eat. We also m...
