(b) The Reynolds number is a dimensionless group defined for a fluid flowing in a pipe as Re = Dup/μ where D is pipe diameter, u is the fluid velocity, p is the fluid density, and is the fluid dynamic viscosity. When the value of the Reynolds number is less than 2300, the flow is laminar-that is, the fluid flows in smooth streamlines. For Reynolds numbers above 2300, the flow is turbulent, characterized by a great deal of agitation. Liquid ethylene glycol flows through a pipe with an inner diameter of 6,51 inches at an average velocity of 0.651 ft/s. At the fluid temperature of 20°C, the density of the liquid is 1.097 g/cm³ and the viscosity is 18.2 centipoise. Determine the value of the Reynolds number and whether the flow is laminar or turbulent.
3.53. WP Two mercury manometers, one open-end and the other sealed-end, are attached to an air duct. The reading on the open-end manometer is 25 mm and that on the sealed-end manometer is 800 mm. Determine the absolute pressure in the duct, the gauge pressure in the duct, and the atmospheric pressure, all in mm Hg.

Suppose that in a coating process a solid sheet immersed in a liquid is pulled steadily at velocity U through a slot in a die, as shown in the figure. The die dimensions are such that there is a liquid gap of thickness H on each side of the sheet. Far downstream from the die the coating has a final thickness H... The pressure in the upstream liquid is ambient (P = Po) and gravitational and surface tension effects are negligible. The die length is L and the system width is W. The liquid is Newtonian and Re is such that the flow is laminar. Liquid P = Po X Die Liquid Solid Sheet Liquid Die H Gas P = Po Width = W Hoo U (a) Assuming fully developed flow, determine vx(y) for the liquid in the upper gap. Be sure to use the coordinates shown. (b) Determine the force required to pull the sheet through the die. You may assume that the shear force on the sheet in the upstream liquid (x < 0) is negligible. (c) Assuming that H is given, determine H...
A pair of concentric glass cylinders, with diameters of 1 and 1.05 cm, respectively are held together in such a way that both annular ends are open to the flow of fluids. The pair of cylinders with its axis vertical are so placed that the open end is slightly below the surface of a reservoir of silicone oil at 25 deg. C. What is the expected height of the oil into the annular space between the cylinders? Take o=0.019 N/m and p=900 kg/m³.
Help with the following question. Please answer all parts of the question
The atmospheric lapse rate on a particular day is constant in the lower part of the atmosphere. At ground level, the pressure is 1020 mBar and the temperature is 15°C. At a height z1 the pressure and temperature are 975 mBar and 11.5 °C. Determine the atmospheric temperature gradient, and the height z1.
2C.4 Falling-cylinder viscometer (see Fig. 2C.4). A falling-cylinder viscometer consists of a long vertical cylindrical container (radius R), capped at both ends, with a solid cylindrical slug (ra- dius KR). The slug is equipped with fins so that its axis is coincident with that of the tube. One can observe the rate of descent of the slug in the cylindrical container when the lat- ter is filled with fluid. Find an equation that gives the viscosity of the fluid in terms of the ter- minal velocity of the slug and the various geometric quantities shown in the figure. Cylindrical slug descends- with speed t -XR- Cylindrical container filled with fluid Fig. 2C.4 A falling-cylinder viscom- eter with a tightly fitting solid cylin- der moving vertically.
