Q2 It is proposed to design a crburettor for Maruti Car. The four strok petrol engine has a displacement (swept) of 796 cm³ and develops maximum Power at 5500 rev/min. The volumetric efficiency at this speed is assumed to be 70% and the air-fuel ratio is 13.5:1.It is expected that at peak power the theoretical air speed at the choke will be 105 m/s. the coefficient of discharge for the venturi is assumed to be 0.85 and that of the main petrol iet is 0.66. An allowance should be made for the emulsion tube, the diameter of which can be taken as 1/2.5) of the choke diameter. The petrol surface is 6mm below the choke at this engine condition. Calculate the sizes of a suitable choke and main jet. The specific gravity of petrol is 0.74. Atmospheric pressure and temperature are 1 bar and 27°C respectively. [Answers 21.3 mm, 1.183 mm ] .

A Q1 A simple carburetor is designed to supply 5 kg of air and 0.40 kg of fuel per minute to the four stroke single cylinder petrol engine. The ambient air is at 1 bar and 25 °C. (a) Calculate the throat diameter of the choke when the velocity of air is limited to 90 m/s. Take pf= 740 kg/m³ and velocity coefficient = 0.8. (b) If the pressure drop near the fuel nozzle is 75% of that 85 at the venturi; calculate the fuel nozzle diameter. Take Car= 0.6. Q2/ For a single jet carburetor drive an expression for the air flow, fuel flow, and the air fuel ratio, take the compressibility of the air into account. Quiz A simple carburetor has to supply 4 kg of air/min at a pressure of 1 bar and at the temperature 27 °C.

A centrifugal pump has a suction pipe with a diameter of 100 mm, and adelivery pipe with a diameter of 75 mm. When discharging 15 L s -1of water, the inlet water pressure recorded is a vacuum of 198 mm Hg. The delivery pressure gauge, placed at 200 mm above the pump inlet, recorded apressure of 0.95 bar. As a reminder:1 bar = 750 mm Hgdensity of water = 1000 kg m -3 Calculate the total head losses, Ht (i.e., the rise in total head) and considering that the measured input power is 3.2 kW, calculate thepump efficiency.
2.5-L bench scale bioreactor is used for the production of recombinant P64K protein from Neisseria meningitides. The dimensions for the bioreactor are Dt 12.9 cm, ratio Di/Dt = 1/3 and N = 700 rpm. With the scale up factor of 2.24, determine the impeller tip speed (m/s) for the pilot scale bioreactor based on constant impeller tip speed and constant power consumption per volume. Predict which scale up method might give a higher concentration of P64K, if the demand of dissolved oxygen plays an important role.
