How does the kinematic viscosity of (a) liquids and (b) gases vary with temperature?

What is viscosity? What causes viscosity in liquids and in gases? Is dynamic viscosity typically higher for a liquid or for a gas?

What is the kinetic energy correction factor? Is it significant?

The uranium ores of the Athabasca Basin deposits of Saskatchewan, Canada, are unusually pure, containing up to 70, uranium oxides. Why doesn’t this uranium ore undergo an explosive chain reaction?

What is a Newtonian fluid? Is water a Newtonian fluid?

A cylindrical tank of methanol has a mass of $60 \mathrm{~kg}$ and a volume of $75 \mathrm{~L}$. Determine the methanol's weight, density, and specific gravity. Take the gravitational acceleration to be $9.81 \mathrm{~m} / \mathrm{s}^2$. Also, find how much force is needed to accelerate this tank linearly at $0.25 \mathrm{~m} / \mathrm{s}^2$.

What is forced convection? How does it differ from natural convection? Is convection caused by winds forced or natural convection?

What is specific gravity? How is it related to density?

A projectile is fired at an inclination of $45^{\circ}$ to the horizontal, with a muzzle velocity of 100 feet per second.The height h of the projectile is modeled by $h(x)=\frac{-32 x^{2}}{(100)^{2}}+x$ where x is the horizontal distance of the projectile from the firing point. Find the maximum height of the projectile.

A fluid that occupies a volume of 24 L weighs 225 N at a location where the gravitational acceleration is $9.80 m/s^2.$ Determine the mass of this fluid and its density.

In 2004, 10-year-old Tilly Smith was vacationing with her family at a beach resort in Thailand. She is credited with saving approximately 100 lives shortly after the magnitude 9 Indian Ocean earthquake. How did she save so many people? (1) She told her family to spend an extra week at the beach. (2) She recognized the signs of an approaching tsunami and warned the people. (3) She predicted exactly when the earthquake would occur. (4) She convinced the people to avoid eating before going swimming.
