How do you find the average of a Nusselt number? In Fluent the surface nusselt number is calculated based upon the formula ((h_eff*L_ref) / k) where h_eff is heat transfer coefficient and L_ref is reference length which you define in refernce values panel and k is thermal conductivity. What is the Nusselt number used for? […]
When making a turn you must signal continuously for at least before reaching the intersection?
When making a turn you must signal continuously for at least before reaching the intersection? Before you stop, turn or change lanes, let the other drivers know what you are going to do by signaling. You can signal with your hand and arm or with your vehicle’s turn signals and brake lights. You should signal […]
How do you test voltage drop in a circuit?
Which bearing can handle greater loads?
Which bearing can handle greater loads? Roller bearings Why do roller bearings have higher loading capacities than ball bearings? Similarly constructed as ball bearings, roller bearings have line contact rather than point contact, enabling them greater capacity and higher shock resistance. Spherical roller bearings can accommodate misalignment and more thrust, and, when doubled up, thrust […]
What happens when natural gas is compressed?
What happens when natural gas is compressed? During compression, the following occurs: As the pistons advance, the volume within the cylinder is reduced, increasing the pressure and temperature of the gas. At a certain pressure, the discharge valves open. The pressure remains fixed while the volume decreases for the rest of the advancing stroke. What […]

What does it take to launch a rocket into space?
What does it take to launch a rocket into space? The Short Answer: We launch things into space by putting them on rockets with enough fuel — called propellant — to boost them above most of Earth’s atmosphere. Once a rocket reaches the right distance from Earth, it releases the satellite or spacecraft. Is it […]

What are the steps in powder metallurgy?
What are the steps in powder metallurgy? Powder metallurgy consists three distinct steps, i.e., (1) mixing metal and reinforcement powders, (2) powder compaction to produce green materials, and (3) sintering usually followed by a deformation process such as hot extrusion (Matli et al., 2017). Which of the following is related to powder metallurgy? Explanation: Copper […]
How does size affect vapor pressure?
How does size affect vapor pressure? Volume does not affect vapor pressure ! The liquid in a container is in equilibrium with the vapor. When the volume is changed, for example – decreased, some of the vapor in the container turns into it’s liquid state. Furthermore, if the volume is increased, some of the liquid […]
