Fuel Tank sloshing sound - Prevention | Purpose of baffle plate in Fuel Tank

Sometimes you can hear the sloshing sound in fuel tank , while driving through a road with more bumps or while bringing down the vehicle in a slight slope and applying brakes.

There are two main reasons for hearing the fuel sloshing sound inside the passenger cabin.

1. The amount of fuel inside the tank is low. For example, if the tank capacity is 30 litres and you have just 2 to 3 litres fuel in the tank, then you many hear this fuel sloshing sound under some circumstances.
2. The design inside the fuel tank is one of the main reason for the sloshing sound. In modern day cars, there is an additional plates placed inside the fuel tank in such a way that prevents fuel movement largely while braking. If the fuel tank , does not has such baffle plate designs inbuilt, then it may leads to fuel sloshing sound.

The baffle plates could prevent the sloshing effect upto certain level, but it is completely not possible to prevent the sloshing sound.

And even in some cases, the absence of baffle plate will result in shifting the centre of gravity of the vehicle while driving in hill areas etc, which may result in poor control & driveability.

Is DWG a CAD file | CAD basics about different drawing file extensions

Generally in AutoCAD & NX , the drawing file is store in DWG format. DWG format file is one of the CAD file .

If we create a drawing sheet in NX or AutoCAD, we can save it in DWG format. But there might be some data loss or data inaccuracy if we transfer the dwg file from AutoCAD to NX or vice versa.

Other CAD softwares like Catia, Solidworks, Solid Edge, ProE etc uses different file extensions for drawing.

Catia stores the drawing sheet with extension .Catdrawing

ProE stores the drawing sheet with extension .drw

SolidEdge stores the drawing sheet with extension .dft

Solidworks stores the drawing sheet with extension  .eDRW

The CAD drawing files created in a specific CAD software cannot be directly opened in other CAD software. Either we should export it into a neutral file format like AutoCAD drawing or the software should have importing license for the specific file format.

What is CAD promotion in Catia V5 and V6 | Part Promotion in Catia

 Part promote is a part of release process in Catia Enovia PLM. In the terms of Life cycle management, "Promote" generally refers to pushing the object to next stage of the work flow by getting proper approvals assigned in the system.

Specific to Part Promotion in Catia PLM, when an user promote a part , it will be considered as moved to Mature stage.

The matured part once frozen could not be demoted by the General CAD user. The intervention of Enovia PLM administrator is required to modify the status in such a case.

In certain circumstances, the user can recieve an error while promoting the part, "Change Maturity status failed, User do not have rights to proceed with this operation for current maturity status of the object, promotion Failed"

One of the main reason for "Part Promotion Failed" is the user will not have the rights that he tries to promote. It is always best practice to ensure that the user is the owner of the instance and reference to all other child objects.

And also it is mandatory to enter the values linked with PDEF , PDD properties , if they are defined in the WEB. The user can ensure to enter thickness, material properties etc in such a case.

What does PID means in Matlab

 In Matlab, PID refers to Proportional Integral Derivative.

PID controlerl is one of the familiar blocks used in Matlab for Industrial automation.

Working of PID controller:

The PID controller will produce a control signal as the output by combining all three Proportional Integral and Derivative controllers.

If it is used a feedback controller, then it will pass the signal at desired level set by the user.

In Industrial Automations, PID controller device is used to regulate temperature, pressure etc.

PID tuning is the process in which the PID is adjusted in such a way to give the quickest response of the output

Radiator Coolant Topup - Which is the bestway Manual vs Pressurized Pump filling

 Sometimes , Engine coolant loss may happen due to various reasons like loss due to minor splashing through radiator accessory tank aka no loss tank's vent hole, coolant loss while replacing the inlet or outlet radiator hose, coolant loss due to hose damage or evaporation of coolant (which is not common nowadays)

If you are caught in an emergency situation in the mid of the journey,  you can topup with ordinary water to survive to the nearest mechanic shop. But first try to bring the mechanic to the breakdown point instead of moving your vehicle.

Now coming to the topup of coolant liquid, you can either fill the coolant manually through the radiator cap or no loss tank cap. Be very cautious while opening the radiator cap, since your coolant might be boiling inside with some pressure accumulated if your car is just stopped. Better wait for some time to cool the engine. Once the cap is removed, pour some coolant through the radiator cap until it fills, once it is filled start the engine and keep idling for 10 to 20 seconds, now you can pour some more through radiator cap. Repeat this until the radiator cap opening is filled. 

Now, close the radiator cap and slighty press the accelerator pedal in 5 seconds frequency, and topup the coolant in no loss tank upto maximum level.

Keep the engine idling and some pressing of accelerator pedal in 5 seconds frequency. Now , you can see the level of coolant is reduced in no loss tank. Now, again topup the noloss tank.

The whole process will take approximately 15 minute . Do not rush, approach the process in a safe manner .

On the other hand,Luckily, if you reached the Garage for topup, if they have the pressurized vaccum coolant refilling machine,  then the machine will pull out the existing coolant completely and fill out the new coolant through the raidator cap opening.

Chiari - Malformation Disease - Symptoms & Effects

Chiari is a neurological disorder in which the skull of a person is too small for his brain to accomodate. 

Because there is not enough room, the bottom part of the cerebellum pushes through the foram magnum onto the brain stem and spinal cord causing compression. 

Compression causes a block in cerebral spinal fluid to the brain, and pressure build up. The pressure is not a 'headache' , it is a blockage of fluid to the brain. There is no cure. Chiari can affect every part of the body because everything is controlled by the brain stem. 

Chiari is progressive. Surgery is to stop progression, but only has a 50/50 chance of improving symptoms already present. Chiari can paralyze the affected person, chiari can suppress your breathing if brainstem damage is extensive. 

Chiari comes with a lot of connecting conditions such as elhers danlos, syringomyelia, iih and POTS to name a few Chiari will forever be part of the life, and it isn't just a "headache," There are over 150 symptoms that can go with chiari and comorbid conditions. 

Chiari is not well known in the medical community but sharing info helps it become more well known. Be your own advocate, and fight for the care you deserve.
