1. (4 points) The inlet of a two-dimensional duct, shown below, is of width b and contains frictionless fluid of constant density p. The velocity in one half of the duct is Ui and the other half is 0.5U1. The two streams do not mix. The outlet of the duct is of width 0.5b. The flow is parallel at the duct entrance and exit, so that the pressure is uniform across the two sections. By...

Fundamentals-of-Compressible-Fluid-Dynamics Balachandran CHAPTER 4 6. A conical diffuser of 15 cm has an area ratio of 4. If the pressure, temperature and velocity at the inlet section are 0.69 bar, 340 K and 180 m/s, estimate the exit pressure and exit velocity. What will be the change in impulse function. [Ans. p2 = 0.8074 bar; V2 = 45 m/s; F2 - F1 = 4167.5 N] 7. The Mach number at inlet and exit of a supersonic diffuser are 3 and...

1. 1.08x106 grams/h of a superheated fluid flows through a pipe in a power plant. The pipe is 1000 cm long, has an inner diameter of 0.05m and a wall thickness of 0.6 cm. The pipe has a thermal conductivity of 0.0017 kW/mK, and the inner pipe surface is at a uniform temperature of 393K. The temperature drop between the inlet and exit of the pipe is 7K, and the constant pressure specific heat of vapor is 2190 J/kgK. If...

Question 4 An orifice plate flow meter, as shown in figure Q4, is situated in a horizontal pipe of 95 cm diameter (d) in which water flows. The pressure difference between the vena contracta and flow upstream at point 1 is measured using a differential manometer. The diameter of the sharp-edged orifice (d.) is 35 cm. The coefficient of discharge for the flow meter is 0.7, and the coefficient of contraction is 0.62. Assume the density...
