A bicycle tire is fi lled with air at an absolute pressure of169.12 kPa, and the temperature inside is 30.0 °C. Supposethe valve breaks, and the air starts to exhaust out of the tireinto the atmosphere (pa = 100 kPa absolute and Ta =20.0 °C). The valve exit is 2.00 mm in diameter and is thesmallest cross-sectional area of the entire system. Frictionallosses can be ignored here; one-dimensional isentropicflow is a reasonable assumption. (a) Find the Machnumber, velocity, and temperature at the exit plane of thevalve (initially). (b) Find the initial mass flow rate out ofthe tire. (c) Estimate the velocity at the exit plane using theincompressible Bernoulli equation. How well does thisestimate agree with the “exact” answer of part (a)? Explain.
The 35°C water flow of the Figure below discharges to sea-level standard atmosphere. Neglecting losses, for what nozzle diameter D will cavitation begin to occur?
Pipe A, 30 cm in diameter, branches into two pipes B and C. Pipe B is 15 cm in diameter and pipe C is 7.5 cm in diameter. If the flow in A is divided as follows 2/3 goes to B and 1/3 goes into C, what is the discahrge in pipe A, if the velocity must not exceed 3 m/s in any of the pipes?
The open stream of water seen in the following picture emerges from a nozzle into the atmosphere at sea level, where it then collides with a stagnation tube. If we exclude losses and assume that the pressure at the centerline of section 1 is 110 kPa, we can estimate that the (a) the mass flow measured in kilograms per second (kg/s), and (b) the height, measured in meters, of the fluid in the stagnation tube.
Water flows upward in a vertical 300-mm pipe at the rate of 0.222 m /s. At point A in the pipe, the pressure is 210 kPa. At B, 4.57 m above A, the diameter is 600 mm, and the lost head A to B equals 1.83 m. Determine the pressure at B.
Assume an inviscid, incompressible flow. Also, standard sea level density and pressure are 1.23 kg/m3 (0.002377 slug/ft3) and 1.01 × 105 N/m2 (2116 lb/ft2), respectively. Consider a venturi with a throat-to-inlet area ratio of 0.8, mounted on theside of an airplane fuselage. The airplane is in flight at standard sea level.If the static pressure at the throat is 2100 lb/ft2, calculate the velocity ofthe airplane.

Consider a venturi with a small hole drilled in the side of the throat. Thishole is connected via a tube to a closed reservoir. The purpose of theventuri is to create a vacuum in the reservoir when the venturi is placed inan airstream. (The vacuum is defined as the pressure difference below theoutside ambient pressure.) The venturi has a throat-to-inlet area ratio of0.85. Calculate the maximum vacuum obtainable in the reservoir when theventuri is placed in an airstream of 90 m/s at standard sea level conditions.
When a viscous, incompressible fluid enters a pipe of radius, R, its velocity is uniform and of magnitude U0. The fluid eventually becomes fully-developed, at which point it has a parabolic velocity profile described by the equation u(r) = Umax[ 1 − ( r/R )^2 ] , where r is the radial distance measured from the center line of the pipe. Determine an expression for the ratio of the max velocity of the fully-developed pipe flow to the uniform inlet velocity, Umax/U0. The fluid is flowing steadily
pls replyy Gasoline (SG-0.7) flows down an inclined pipe whose upper and lower sections are 90 mm (section 1) and 60 mm (section 2) in diameter respectively. The pressure and velocity in section 1 are 280 kPa and 2.3 m/s respectively. If the difference in elevation between the 2 sections is 2.5m, find the pressure at point 2.
For the system below, let the pump exhaust gasoline at 65 gallons per minute to the atmosphere through a 3-cm-dimater opening. When x = 3 m, y = 2.5 m and z = 2 m, the pipe friction head loss along the entire length of the pipe has been shown to be hf = 3.7 V 2 /(2g) empirically, where V is the velocity in the pipe. Estimate the horsepower to be delivered by the pump.
