Draw the neat sketch of a 1-2 shell and tube heat exchanger?
Determine all the view factor for a duct of equilateral triangular cross section. Assume that all surfaces are plane.?
A chamber for heat curing large aluminium sheets, lacquered black on both sides, operates by passing the sheets vertically between two steel plates 150mm apart. One of the steel plates is at 300°C and the other plate is at 25°C. The emissivity of steel plates is 0.56 and the Stefan-Boltzmann constant is 5.67x108 W/(m²-K4). What is the heat transfer rate per unit area between the plates?
Write short notes on pool boiling of saturated liquid with neat sketch of flux vs temperature drop?
Derive the equation for the partial pressure distribution of A and B for diffusion of A through non-diffusion B considering the point z-0 to z-z where the partial pressure of A is PA?
A Test tube, 1.5 Cm in diameter and 12cm long, has 0.4g camphor on it. How long will it take for the camphor (C,H,O) does disappear? The pressure is atmospheric and the temperature is 200C. The sublimation pressure of camphor at this temperature is 97.5 mmHg and the diffusivity of camphor can be estimated by using the fuller' equation. Diffusion volumes: C-16.4, H=1.98, O-5.48, Air 20.1?
