How do you find the heat transfer coefficient of a Nusselt number? Formula Nusselt Number : Nu = hL/k. Convection Heat Transfer Coefficient : k = Nuk/L. Characteristic Length : L = Nuk/h. Thermal Conductivity of the Fluid : k = hL/Nu. Where, Nu = Nusselt Number, h = Convection Heat Transfer Coefficient, L = […]
Why was New Orleans not prepared for Hurricane Katrina?
Why was New Orleans not prepared for Hurricane Katrina? Emergency managers in New Orleans had been debating whether the levee system would work in a major hurricane before Katrina hit. Federal funding cuts left many projects undone and local engineers were not surprised when water surged into New Orleans. How did the federal government fail […]

How can the motion of fluids be described?
How can the motion of fluids be described? There are two ways to describe the fluid motion. One is called Lagrangian, where one follows all fluid particles and describes the variations around each fluid particle along its trajectory. The other is Eulerian, where the variations are described at all fixed stations as a function of […]

Is ammonia heavier than air?
Is ammonia heavier than air? Anhydrous ammonia gas is lighter than air and will rise, so that generally it dissipates and does not settle in low-lying areas. However, in the presence of moisture (such as high relative humidity), the liquefied anhydrous ammonia gas forms vapors that are heavier than air. Do ammonia fumes rise? Most […]
Why does oxygen have a charge?
Why does oxygen have a charge? Oxygen is more electronegative than carbon which attracts the electrons to them usually giving it a negative charge. How will an atom get a charge of +2? A normal atom has a neutral charge with equal numbers of positive and negative particles. Ions are atoms with extra electrons or […]

How do you prevent tire explosions?
How do you prevent tire explosions? Preventing tire explosions: Never heat or weld rims or wheels on a mounted tire, whether it is inflated or not. Use non-flammable tire lubricants and sealants. Remove all foreign objects, such as wood, from tires. Avoid working near power lines. What is the name of the tool used to […]
