1-A counterflow, concentric tube heat exchanger is used to cool the lubricating oil for a large
industrial gas
turbine engine. The flow rate of cooling water through the inner tube (Di = 25 mm) is
0.2 kg/s, while the flow rate of oil through the outer annulus (Do = 45 mm) is 0.1 kg/s. The oil and
water enter at temperatures of 100 and 30 C, respectively. The exit temperature of hot fluid and cold
fluid is 60 and 40 C. calculate the LMTD. Calculate the surface area of the heat exchanger. How

- Assignment 2. Example. The diffusivity of the vapour of a volatile liquid in air can be conveniently determined by Winkelmann's method in which liquid is contained in a narrow diameter vertical tube, maintained at a constant temperature, and an air stream is passed over the top of the tube sufficiently rapidly to ensure that the partial pressure of the vapour there remains approximately zero. On the assumption that the vapour is transferred from the surface of the liquid to the air stream by molecular diffusion, calculate the diffusivity of carbon tetrachloride vapour in air at 321 K and atmospheric pressure from the following experimental data: Time from commencement of experiment, (t x1 03 s) Liquid level (mm) 0.0 0.0 1.6 2.5 11.1 12.9 27.4 23-2 80-2 43.9 117.5 54-7 168.6 67.0 199.7 73-8 289-3 90-3 383-1 104.8 The vapour pressure of carbon tetrachloride at 321 K is 37.6 kN/m² and the density of the liquid is 1540 kg/m³.

Eng. Chem. Res., 27, 2224 (1988)]. TBA was produced by the liquid-phase hydration (W) of isobutene (I) over an Amberlyst-15 catalyst. The system is normally a multiphase mixture of hydrocar- bon, water, and solid catalysts. However, the use of cosolvents or excess TBA can achieve reasonable miscibility.
