Questions (page 2)
Section A
Q2. Countercurrent stripping of ammonia from a dilute solution by air is carried out in a sieve tray column having 6 trays. The equilibrium relationship is given by ye = 0.85 xo. 90 percent of ammonia is removed when the molar flow of air is 1.5 times that of the solution. Rivers are the source of water supply for factories. Water at the rate of 2 imes 105 kg/hr has to be pumped from a river to a factory overhead tank, placed at a height of 25 metres from the river bed, the total length of pipeline being 1500 metres. The iron pipe having an inside diameter of 30 cm has been used for this pumping. The viscosity of river water is 0.764 cP and friction factor is given by f = 0.0014 + (0.125)/(Re0.32). The wall of a furnace is constructed from an inner layer of 0.6 cm thick steel (k = 40 W/mK) and an outer layer of 10 cm brick (k = 2.5 W/mK). The inner surface temperature is 900 K and the outside surface temperature is 480 K. Calculate the heat loss from the furnace per unit area and also the temperature at the interface. Assume steady state exists and effects at the corners and edges of the wall are negligible. The temperatures at the surface are uniform.
(a) Calculate the ideal stages of the column and stage efficiency.
(b) Find the percentage removal, if the air rate of flow is increased to 2 times the solution rate.
(a) Calculate: The Reynolds number (Re), if \rho = 1 gm/cc
(b) The head loss due to friction.
