thermal-hydraulic study of the lbe-cooled fuel assembly in the myrrha reactor: experiments and simulations
For many cutting-edge systems based on fast neutrons, heavy liquid metals (HLMs), such as lead-bismuth eutectic (LBE) and pure lead, are popular candidate coolants.
LBE is employed, in instance, in Mol (Belgiumgroundbreaking )'s MYRRHA fast reactor, which can run in either critical mode or as a sub-critical accelerator-driven system. Key thermal-hydraulic features of these systems, such as the proper cooling of fuel components, must be evaluated with a heavy emphasis on safety.
This flow scenario presents a challenge for computational fluid dynamics (CFD) models, such as those used to relate the turbulent transport of momentum and heat, due to the complicated geometry and low Prandtl number of the LBE (Pr 0.025). Therefore, accurate experimental information is required for validation.

When welding a T-joint, why should the arc be directed more toward the bottom workpiece?
When welding a T-joint, the reason that the arc need to be directed more toward the bottom workpiece is so that a person can hinder or stop any form of undercutting of the given top piece.
What is the ideal welding position for any joint?The Positioned flat of the flat position weld, often known as a "downhand" position, is the simplest and frequently the first weld that new pupils learn.
The welder places the metals to be welded flat and moves the electric arc across them while it travels across the workpiece in a way that is said to be an horizontal orientation.
Therefore, based on the above, When welding a T-joint, the reason that the arc need to be directed more toward the bottom workpiece is so that a person can hinder or stop any form of undercutting of the given top piece.

(5 points) Some strands of Christmas tree lights are sometimes wired in series. What happens to the other lights if one of the series bulbs is removed? Other lights are sometimes wired in parallel. What happens when one of these parallel bulbs is removed? Explain why
Answer:
Series: All the lights go out
Parallel: Nothing happens
Explanation:
Often referred to as ‘daisy-chained’ or ‘looped’ the current in a series circuit follows one path from start-to-finish with the Anode (positive) of the second LED connected to the Cathode (negative) of the first. The image to the right shows an example: To wire a series circuit like the one shown, the positive output from the driver connects to the positive of the first LED and from that LED a connection is made from the negative to the positive of the second LED and so on, until the last LED in the circuit. Finally, the last LED connection goes from the negative of the LED to the negative output of the constant current driver, creating a continuous loop or daisy chain. When one goes out, the whole strand of light stops working with it.
Parallel circuit (when lights are wired in parallel):
Where a series circuit receives the same current to each LED, a parallel circuit receives the same voltage to each LED and the total current to each LED is the total current output of the driver divided by the number of parallel LEDs.
In a parallel circuit all the positive connections are tied together and back to the positive output of the LED driver and all the negative connections are tied together and back to the negative output of the driver. Lets take a look at this in the image to the right. Using the example shown with a 1000mA output driver, each LED would receive 333mA; the total output of the driver (1000mA) divided by the number of parallel strings (3).

If both the ram air input and drain hole of the pitot system become blocked, the indicated airspeed will: a) increase during a climb.
What is a ram air input?A ram air input can be defined as an air intake system which is designed and developed to use the dynamic air pressure that is created due to vehicular motion, or ram pressure, in order to increase the static air pressure within the intake manifold of an internal combustion engine of an automobile.
This ultimately implies that, a ram air input allows a greater mass-flow of air through the engine of an automobile, thereby, increasing the engine's power.
In conclusion, indicated airspeed will increase during a climb when both the ram air input and drain hole of the pitot system become blocked.

technician a says that gasoline engines have spark plugs to ignite the air-fuel mixture.technician b says that diesel engines use compression to ignite the air-fuel mixture. who iscorrect?
It is right to state that Technician B is correct. A piston compresses the air in the cylinder, causing it to become very hot. The diesel is then atomized in the injectors and sprayed into the heated air as a mist. The heated air ignites the gasoline quickly, creating ignition.
What is compression in Engines?As the fuel injectors drive air and fuel into the combustion chamber, compression occurs in the internal combustion cylinders.
The mixture ignites, and the piston is driven by the expansion of the burning gases in the cylinders, converting the energy from combustion into mechanical energy that propels the vehicle.
