Fluid motion induced by surface tension variation is called the Marangoni effect. Fluid motion induced by surface tension variation is called the Marangoni effect Consider a liquid layer of thickness h on a solid flat plate. The liquid is exposed to ambient air but the surface tension σ is not constant. It varies longitudinally (in the x direction) due to a temperature gradient, which induces the liquid to move along the interface I. Write the governing equations for the liquid...
a. (2 pts.) The film temperature, used to evaluate properties, for internal flow is the average of the surface temperature and the external free stream fluid temperature. True or False. 1. b. (2 pts.) The local convection coefficient, h, around the circumference of a cylinder in cross flow is constant (it does not vary with position as you travel around the cylinder.) True or False c. (2 pts.) For internal fully developed flow the convection coefficient, h, decreases as the...

Which of these properties of water makes it a good solvent for a variety of substances? Select one: a. its high specific heat. b. Its boiling point c. its hydrogen bonding ability d. Its high surface tension
The Buoyant Force is calculated by (fluid density)(volume of displaced fluid)(acceleration due to gravity). How does changing the shape of an object relate to the Buoyant Force and the object's density? A. By changing the shape of the object we manipulate both the weight of displaced fluid and the density of the object. Thus we can change the Buoyant Force on the object and change the density, making it possible for heavy objects to float, hover or rise in a...
