The venturi of the simple carburetor has a throat diameter of 25 mm and coefficient of air flow is 0.85. The fuel orifice has a diameter of 1.5 mm and the coefficient of fuel flow is 0.66. The fuel surface is 6 mm below the throat. a) Find the air fuel ratio for a pressure drop 0.08 bar when the nozzle lip is neglected. b) Minimum velocity of air to start the fuel flow when the nozzle lip is taken into account. Take the density of air and fuel as 1.2 kg/m3 and 750 kg/m3

Air is injected into a 50 m long horizontal pipeline (of 42 mm diameter) carrying a clay slurry of density 1452 kg/m 3 . The rheological behaviour of the slurry follows the power-law model, with m = 5.55 Pa sn and n = 0.35. The volumetric flow rates of air and liquid are 7.48 and 1.75 m3 /h, respectively. The air is introduced into the pipeline at 20°C and at a pressure of 1.2 bar. Ascertain the flow pattern occurring...

column 0.6 m diameter and 6 m high is packed with 25 mm ceramic Raschig rings and used in a gas absorption process carried out at 101 KPa and 300 K. If the liquid and gas properties approximate to those of water and air (water viscosity=1 mNs/m2, air viscosity=0.02 mNs/m2) and their flowrates are 2.4 and 0.95 kg/m2s respectively. The packing properties are the following: voidage (e) is 0.71, specific surface area (S) is 190 m2/m3. Calculate the wet pressure...
Air under standard conditions (ñ=1.23 kg/m3, µ=1.79 x 10 -5) flows through a 4- mm diameter...
Air under standard conditions (ñ=1.23 kg/m3, µ=1.79 x 10 -5) flows through a 4- mm diameter drawn tubing with an average velocity of V = 50 m/s. For such conditions the flow would normally be turbulent. However if precautions are taken to eliminate disturbances to the flow (the entrance to the flow is very smooth, the air is dust free, the tube does not vibrate etc.), it may be possible to maintain laminar flow. What is the pressure drop in...

An aluminum transmission line with a diameter of 20 mm has an electrical resistance of R'elec= 2.636 × 10-4 Ω/m and carries a current of 700 A. The line is subjected to frequent and severe cross winds, increasing the probability of contact between adjacent lines, thereby causing sparks and creating a potential fire hazard for nearby vegetation. The remedy is to insulate the line, but with the adverse effect of increasing the conductor operating temperature. (a) Calculate the conductor temperature...
