DEPARTMENT OF CHEMICAL ENGINEERING Reaction Engineering CGC035 / CGC052 Problem Sheet 3 - Fluid-fluid reactions 1. The reaction rate for the heterogeneous reaction A(g) + B(l)→ products is second order according to the expression -rA=kCACB and it is relatively slow compared to mass transfer so it takes place in the bulk of the liquid. Combine the following rate expressions for diffusion through the gas and liquid films‚ -rA=kAga(pA-pAi) and -rA=kAlaCAi-CA‚ with Henry’s law pAi=HACAi

Aeronautical Engineering My long-standing fascination with aircrafts began with my favourite toy helicopter. Since then I have made a model plane of a radio controlled spitfire Mk2 and managed to fly it. My fascination has been followed up with literature and resources; further developing my understanding and interests in the architecture of an aircraft. Books such as ’The Aerospace Chronology’ provided some insight into technological advances that have produced safer‚ faster and more agile planes
