How does lubricating a machine affect the output work from that machine?

How does lubricating a machine affect the output work from that machine?

Infer how lubricating a machine affects the output force exerted by the machine. Friction is a force that opposes the motion of two surfaces sliding past each other. Lubrication a machine increases the output force because it decreases friction. The mechanical advantage of a machine is less than one.

What is the efficiency of a machine?

The efficiency of a machine is equal to the ratio of its output (resistance multiplied by the distance it is moved) to its input (effort multiplied by the distance through which it is exerted); it is also equal to the ratio of the AMA to the IMA.

Why can’t a real machine ever have 100% efficiency?

Machines are not 100% efficient because some of the work done by a machine is used to overcome friction. So work output is always less than work input. Work: Done by machines is calculated as Mechanical Advantage which is Output Force divided by Input force.

What is a typical fan efficiency?

Fan Efficiency Typical motor and belt efficiencies: Motor 1kW – 0.4. Motor 10 kW – 0.87. Motor 100 kW – 0.92.

Do register boosters work?

A properly-designed HVAC system—which includes the vents and ductwork—should provide sufficient heating and cooling throughout the house, regardless of distance from the heating and cooling systems. While duct booster fans do boost airflow in specific areas, they don’t solve the underlying problem.

Can you put 2 inline fans together?

Mounting two fans inline with each other increases the “torque” of the airflow but does not increase the maximum unrestricted flow. If you put two of the same fans facing the same way on either side of a 2′ tube, the airflow would be roughly the same as if there was only one.

Can two bathroom fans share a vent?

Well, you can’t! You’d often blow air from one bathroom into the other, and local building inspectors wouldn’t approve it. But while you can’t have two fans with one vent, you can make one fan and one vent serve two bathrooms. A grille in each bathroom attaches to ducts, which then fasten to a “Y” connector at the fan.

What happens when you put two fans together?

In general, combining axial fans in series does not increase the airflow but increases the air pressure. When an increased air volume or pressure becomes necessary for an application, multiple fans can be used instead of replacing a single fan with a larger capacity fan.

How many fan splitters can I use?

TWO fans

Can I add an extra fan to my PC?

Yes, it’s fine to plug a 3 pin case fan cable into a 4 pin header on the motherboard, but just make sure you’re inserting the cable into the correct 3 pins (they should easily slide in without too much force). It’s also fine if you have to connect a 4 pin case fan cable into a 3 pin motherboard header.

Can you double stack PC fans?

Yes and no. Putting two fans together does not increase the maximum airflow of the fans. So if you have a fan that pushes 50cfm in a theoretical, no resistance situation, putting two of them together will still only push 50cfm. What stacking can do though is help overcome resistance to the fan.

How can I make my fan work better?

You can enhance the effect by placing ice packs atop the fabric, and occasionally re-wetting it with cold water – be careful to keep any running liquid well away from the fan. Alternatively, you could skip the fabric and place ice or ice packs directly in the airflow in front of the fan.

Can you Overcool a CPU?

There is no way to overcool a cpu – that’s just nonsense. Whether you should add the side fans should be dictated by your temperatures.

What is push pull fan setup?

What is push-pull? It is a setup where the radiator is sandwiched between 2 sets of fans, which blow in the same direction.
