Which fluid requires more energy to maintain flow ?
a. Non viscous fluids b. High viscosity fluids
Homework Answers
b) High Viscosity fluids
as in viscous fluids energy gets dissipated as heat durin the motion so more energy is requred

Which of the following is NOT a mechanism to maintain the body's internal temperature? A. Fluid has a high capacity for heat, so it requires a great deal of energy to raise its temperature. B. Fluid is evaporated as sweat from the skin's surface, thus cooling the body. C. Warmed fluids from the body's surface return to the body's core, thus heating the body. D. Fluid acts as a coolant by increasing the blood flow from the warm body core...

What does Δp = QR mean in words? Pushing a viscous fluid through a pipe requires a drop in pressure along the direction in which the fluid is flowing through the pipe. If there is no pressure difference across a pipe, the flow is 1/R. If you increase the flow of a viscous fluid, you increase the pressure at the end of the pipe toward which the fluid if flowing. A viscous fluid will always move more and more quickly...

Assuming both non-circular cylinders are experiencing the same
external fluid flow (identical density, viscosity, fluid velocity),
which orientation would experience a higher convective heat
transfer coefficient? What is the ratio of Nusselt numbers for the
flat cross-section over the angled cross-section? Please show work,
and explain conceptually if possible. Thank you!

According to Bernoulli's principle, all other things being equal, for a non-viscous incompressible fluid undergoing streamline flow: b) The greater the density of a fluid, the greater the buoyant force on any object submerged in the fluid. C) The pressure in a fluid is lower where the fluid is moving faster D) Air moves faster over an airplane wing than it does under. E) The deeper the position in an incompressible fluid, the greater the density of the fluid.

Any object moving in a fluid experiences a drag or viscous force opposing its motion. Assume the object is spherical and the flow around it is laminar. For an object of radius 0.25m moving in honey at 70F (viscosity 20 Pa.s), what is the drag force at a speed of 0.1 m/s? If the object is moving horizontally and at the same constant speed of 0.1 m/s, a force must be exerted on it to maintain that motion. That means...

2) (35 points) It is a common practice when examining a fluid's viscous behavior to plot the shear strain rate (velocity gradient) dv dy on the abscissa versus shear stress (t) on the ordinate. When a fluid has a straight-line behavior between these two variables it is called a Newtonian fluid, and the resulting relationship is where u is the fluid viscosity. Many common fluids follow this behavior such as water, milk, and oil. Fluids that do not behave in...
