The air is at a pressure of 1.013 bar and a temperature of 27 °C. Calculate the throat diameter of the choke for air flow velocity of 90 m/sec. Take velocity coefficient to be 0.8. Assume isentropic flow and the flow to be compressible. Quiz/ Determine the air-fuel ratio supplied at 5000 m altitude by a carburetor which is adjusted to give an air-fuel ratio of 14:1 at sea level where air temperature is 27 °C and pressure is 1.013 bar. The temperature of air decreases with altitude as given by the expression The air pressure decreases with altitude as per relation h = 19200 log10 (1.013), where P is in bar. State any assumptions made. t = ts P 0.0065h

What would be the effect on the result of the following systematic errors of measurement! a. The jockey weight in error by 0.001kg. b. The distance from the center of the vane to the pivot of the lever in error by 1mm. C. The diameter of the water jet emerging from the nozzle 0.1mm different from the nozzle diameter. It has heen assumed that the velocity in the let is uniform over the entire cross section.

The first compressor blade pair in a turbojet is to be designed with symmetric blading. If the inflow to the compressor has a gas speed measured as 108m/s, for this speed the shaft is designed to rotate at 262rad/s, and the mean blade radius of this first blade row is 0.51m, to what angle should the first stator be set? Express your answer in degrees.

centrifugal compressor has pressure ratio of 4:1 with an isentropic efficiency of 80% when running at 15000 rpm and inducting air of 293° K. Curved vanes at inlet given the air a pre whirl of 25° to the axial direction curved vanes at inlet given the air a pre whirl of 25° to the axial direction at all radil and mean dia of eye is 250 mm. The absolute air velocity at inlet is 150 m/sec. Impellér tip dla 600 mm calculate slip

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 ] .

How Vt=Vr × sin (70°) ? i need explanation regarding it. Please provide a solution within 10-20min

The static head corresponding to a flow velocity of 10 m/S

Provide average and instantaneous velocities formulas.

For the single pump-pipe system below, what will be the changes for the operating point if we increase the pipe size but decrease the shaft speed of the pump? EB H₂ O The operating point will remain the same. O The operating point will occur either at a higher discharge or at a lower discharge, depending on the specific influence of each change. O The operating point will occur at a higher discharge. O The operating point will occur at a lower discharge.

A gear pump has a 80-mm outside diameter, a 55-mm inside diameter, and a 25-mm width. If the actual pump flow rate at 2300 rpm and rated pressure is 140 LPM, calculate the Displacement Volume, VD (m3) Group of answer choices 66.9x 10-7 m3 56.3 x 10-6 m3 66.3 x 10-6 m3 97.1 x 10-7 m3 70.9 x 10-6 m3
