| shikha | Re: GATE Papers by IIT Bombay The previous year Graduate Aptitude Test in Engineering (GATE) question paper of CH: Chemical Engineering subject is as follows: For a pure liquid, the rate of change of vapour pressure with temperature is 0.1 bar/K in the temperature range of 300 to 350 K If the boiling point of the liquid at 2 bar is 320 K, the temperature (in K) at which it will boil at 1 bar (up to one decimal place) is Three identical closed systems of a pure gas are taken from an initial temperature and pressure (T1, P1) to a final state (T2, P2), each by a different path. Which of the following is ALWAYS TRUE for the three systems? (∆ represents the change between the initial and final states; U, S, G, Q and W are internal energy, entropy, Gibbs free energy, heat added and work done, respectively.) (A) ∆U, ∆S, Q are same (B) W, ∆U, ∆G are same (C) ∆S, W, Q are same (D) ∆G, ∆U, ∆S are same For a gas phase cracking reaction A → B + C at 300C, the Gibbs free energy of the reaction at this temperature is ∆G = 2750 J/mol. The pressure is 1 bar and the gas phase can be assumed to be ideal. The universal gas constant R = 8.314 J/mol.K. The fractional molar conversion of A at equilibrium is: (A) 0.44 (B) 0.50 (C) 0.64 (D) 0.80 Two different liquids are flowing through different pipes of the same diameter. In the first pipe, the flow is laminar with centerline velocity, ����max ,1, whereas in the second pipe, the flow is turbulent. For turbulent flow, the average velocity is 0.82 times the centerline velocity, ����max ,2. For equal volumetric flow rates in both the pipes, the ratio ����max ,1/����max ,2 (up to two decimal places) is A cylindrical packed bed of height 1 m is filled with equal sized spherical particles. The particles are nonporous and have a density of 1500 kg/m3. The void fraction of the bed is 0.45. The bed is fluidized using air (density 1 kg/m3). If the acceleration due to gravity is 9.8 m/s2, the pressure drop (in Pa) across the bed at incipient fluidization (up to one decimal place) is GATE Chemical Engineering Question Paper    |
