Description

Summary This experiment was carried out as part 4 of a series of experiments for the Fluids and Separaton Module. In this experiment we looked at Weted Wall Columns because they are very important and chemical and process engineering as they assist heavily in the study of mass transfer and industry they are used for mass transfer that involves high rates of heat transfer. The aim of the experiment was to form the variaton of mass transfer coefcients of humidifcaton of air with air fowrate and the other aim was to arrive at a correlaton between mass transfer coefcient and neynolds number for both laminar and turbulent fow The experiment was carried at London South Bank University Petroleum Lab 127.The lab was equipped with three vertcal tubes with measurements of (i) 4.1 cm internal diameter, 74 cm high (ii) 2.1 cm internal diameter 64.5 cm high (iii) 4.1 cm internal diameter. To take our measurements a rotameter was provided for measure the fow of air and thermometer were also provided for measuring wet and dry bulb temperature.
