Textbook Question
Chapter 7, Problem 62P
Consider water flow around a circular cylinder, of diameter D and length l. In addition to geometry, the drag force is known to depend on liquid speed, V, density, ρ, and viscosity, μ. Express drag force, FD, in dimensionless form as a function of all relevant variables. The static pressure distribution on a circular cylinder, measured in the laboratory, can be expressed in terms of the dimensionless pressure coefficient; the lowest pressure coefficient is Cp = −2.4 at the location of the minimum static pressure on the cylinder surface. Estimate the maximum speed at which a cylinder could be towed in water at atmospheric pressure, without causing cavitation, if the onset of cavitation occurs at a cavitation number of 0.5.

By applying Buckingham Pi’s Theorem, determine an equation forTa as a function of the radius of inner cylinder (r), cylinder tangential velocity (v),fluid dynamic viscosity (μ), gap distance (L) and fluid density (ρ).

- 1) At any time, approximately 20 volcanoes are actively erupting on the Earth, and 50–70 volcanoes erupt each year. Over the past 100 years, an average of 850 people have died each year from volcano eruptions. As scientists and engineers study the mechanics of lava flow, accurately predicting the flow rate (velocity) of the lava is critical to saving lives after an eruption. Jeffrey's equation captures the relationship between flow rate and viscosity as: Flow V = Pgt sin(@) 28 сm 10 where p is the density of the lava, g is gravity, t is the flow thickness, a is the slope, and u is the lava viscosity. Typical values are given as follows for the flow rate: u= 4x103 kg/(m.s) ±1% p= 2.5 g/cm³ ±1% t= 28 cm +0.5 cm a= 10° +1 ° g= 9.81 m/s? Determine the likely maximum possible error in the calculated value of the flow rate.arrow_forwardThe property of a fluid called viscosity is related to its internal friction and resistance to being deformed. The viscosity of water, for instance, is less than that of molasses and honey, just as the viscosity of light motor oil is less than that of grease. A unit used in mechanical engineering to describe viscosity is called the poise, named after the physiologist Jean Louis Poiseuille, who performed early experiments in fluid mechanics. The unit is defined by 1 poise = 0.1 (N s)/m2. Show that 1 poise is also equivalent to 1 g/(cm · s). %3Darrow_forwardQ.7.

The plates are 0.025m apart (h). The shear stress 7 is estimated by 2m/sec = 0.025m V 80μ. The viscosity (4) in N – sec/m² is a function of temperature. Laboratory measurements have determined µ at the temperatures shown in the table below: T(°C) | (µ)(N – sec/m² 5 0.08 20 0.015 30 0.009 50 0.006 55 0.0055arrow_forwardThe Reynolds number is a dimensionless group defined as follows for a liquid that flows through a pipe: Re = Dvρ / μ where D is the diameter of the pipe, v is the velocity of the fluid, ρ is its density and µ its viscosity.

For Reynolds numbers greater than 2100, the flow is turbulent, characterized by considerable agitation.
