A venturi tube is used to determine the airspeed at the throat/test section. During the test, a raise of 5 inches of a liquid with a specific gravity of 0.3, was recorded in the instrument. Determine the velocity of the at the (a) smallest and (b) largest section, when the ratio of the area between the largest and smallest section is 6:2.5. Assume incompressible flow and conditions similar to 2000 ft altitude.
A calibration test of a 2.5cm circular sharp edged orifice in the vertical side of the large tank showed a discahrge of 590 N of water collected in 81 seconds, when under a constant head of 4.70 m.

Consider the one-dimensional, incompressible flow through the circular channel shown. The velocity at section 1 is given by U5U0 1U1 sin ?t, where U0 520 m/s, U1 5 2 m/s, and ? 5 0.3 rad/s. The channel dimensions are L51 m, R1 50.2 m, and R2 50.1 m. Determine the particle acceleration at the channel exit. Plot the results as a function of time over a complete cycle. On the same plot, show the acceleration at the channel exit if the channel is constant area, rather than convergent, and explain the difference between the curves.
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.

An incompressible viscous flow is contained between two parallel plates separated from each other by distance b. The flow is caused by the movement of the upper plate which has a velocity U, while the bottom plate is fixed. If U = 9.5 m/s and b = 3.2 cm, and there is no pressure gradient in the flow direction. a) Start with Navier-Stokes equations and determine the velocity at the point x = 7 cm and y= 0.56 cm. b) Calculate the magnitude of the vorticity at the same point. c) Calculate the rate of angular deformation at the same point. Work to 4 significant digits. Enter all values using base units or their combinations, i.e. m, m/s, Pa, N. Do not use multiples as e.g. mm, kPa. You can use values with exponents, such as 0.12e3.

Figure 1) shows a tank of 20∘C water with a nozzle h = 27 cm below the surface. Bernoulli's equation applies to the flow between points 1 and 2 on the streamline, but not to the flow between points 2 and 3.What is the volume flow rate through the nozzle in L/min ? Assume that the water level in the tank is held constant.
