1- If the velocity head is 250 mm then what is the velocity of the fluid.

2-A tube, open at both ends, is placed into water at constant temperature. How high does the water rise within the tube in mm? The diameter of the tube is 10 mm. Assume the contact angle is zero.

3- You measure air to have a velocity of 45 m/s in a pipe of radius 2 cm. The pipe then expands until its cross-sectional area is 17 cm2 . What is the velocity after the expansion?

4- A dam retains water to a depth 50 % of its height. The height of the wall is 15 m. What is the resultant force on the dam, per meter of dam wall width in kN/m?

Fluid X is flowing in a circular pipe with a constant velocity ν (m/s). The fluid is cooled by a jacket kept at constant temperature, Tj. Fluid velocity is plug shaped , in other words uniform at radial positions. Assume that temperature is uniform in radial positions because of turbulent flow conditions; ρ and Cp of the fluid are constants. The inlet temperature (at z=0) is constant and uniform at To (To>Tj). Assume that thermal conduction of heat along the...

Consider a 2-mm-diameter sphere immersed in a fluid at 300 K and 1 atm. (a) If the fluid around the sphere is quiescent and extensive, show that the conduction limit of heat transfer from the sphere can be expressed as NuD,cond = 2. Hint: Begin with the expression for the thermal resistance of a hollow sphere, letting r2 →∞ and then expressing the result in terms of the Nusselt number. (b) Considering free convection, at what surface temperature will the...

An I-section joist 450 mm x 250 mm x 20 mm is used as a strut with one end fixed and the other end free carrying a buckling load of 200 × 106 N. Suggest the changes to be made in the length of the strut for a constant flexural rigidity by considering both the ends to be hinged, both the ends to be fixed and one end fixed but the other end hinged. Compare the values of the safe...

1. What is the difference between the Constant Head and Falling Head Permeability Test? 2. What principal are the two permeability tests based on? 3. Why would one use the falling head tests instead of the constant head test? 4. If you anticipate that the permeability of a soil is approximately 0.000001 cm/sec and the falling head permeability testing equipment had the following dimensions, how long should the test take if the beginning head is 20 cm and the final...
