A large measuring cylinder will be filled to the top with fantastic syrup. this will likely be done little by little and at a shallow perspective so as to stop bubbles via forming which in turn would in any other case compromise the reliability from the results. Seven steel ball bearings of various diameters will be selected and their radii tested using a micrometer. Four indicators, three cm apart from each other, will be placed vertically over the measuring cyndrical tube which will possess five centimetres of thick syrup between the the top of cylinder as well as the first marker.

This five centimetre gap is to allow the ball bearing to reach fatal velocity just before measurements happen to be taken so it passes every marker around the same speed.

Each gun will be assigned a stop-clock so if the ball passes each gun, the appropiate stop-clock will be started swilst the previous time is ended. This will offer three similar times that can be used to find a typical time and velocity for the balls.

The ball bearing will be eliminated after every single experiment in order not to affect the next test.

A CONSIDERED TO SAFETY

* No fantastic syrup will probably be consumes as it may have come in to contact with dangerous materials in the lab so be harmful, harmful or perhaps irritant.

* Any ball bearings that drop on the floor will be instantly picked up thus they are certainly not slipped in.

* Any syrup spills will be cleansed up so they not really present a slipping danger

Equipment

* Steel ball bearings by 2

* Screw determine micrometer = accurate to 0. 01mm

* Gold syrup

5. Measuring cylinder = accurate to 1mm

* Stop clocks times 3 sama dengan accurate to 0. 01mm

Accurracy

Since the true benefit for the viscosity of golden viscous syrup is unfamiliar. I will gauge my precision by the school average. If my value close to the school average however will have the right value intended for the viscosity of fantastic syrup.

Error

Sample period = dua puluh enam. 983

twenty six. 983 sama dengan 26. 980 or 26. 990

If it were to the same 26. 980 then the speed would still round to at least one. 111×10-3

And if it were to equal 26. 990 then a velocity will still round to 1. 111×10-3

The average time is appropriate to zero. 01s due to the combined accuracy and reliability of the three separate occasions. The mistake bars produced for the speed are so small they are really worth no real merit and so were disregarded from the chart of benefits.

Analysis

Stoke’s law declares:

Upthrust & viscous pull = pounds

This is true because if the ball bearing has reached its fatal velocity fat and the quantity of upthrust and viscous drag happen to be equal.

The equation can be re-arranged to achieve the viscosity() of golden viscous syrup.

The density of metallic has been found to be 7647kg/m

The density of viscous syrup has been discovered to be 1490kg/m

By looking in the graphs brand of best fit the gradient have been found being 250

So if we suggestions this info into the equation we get

250=19. 69(7647-1490)

250= 120677. two

9

being unfaithful = 482. 71

two hundred fifity x being unfaithful = 120677. 2 viscosity( ) = 53. 6Nsm-3

9

being unfaithful =120677. 2

250

Bottom line

The viscosity of the golden thick syrup was discovered to be 53. 6Nsm-3

What could have damaged the dependability of the effects?

The awareness of my personal eqiupment: Sketching error bins on my results was considered however as a result of scales used in the graph the ywould not always be useful. The radius was squared to lower to the percentage error of the results taken by the leader however this can not completely remove the error. Also the stopwatches had been only exact to 0. 001 just a few seconds.

The ball bearings would have slid throughout the walls of the cylinder plus the resulting scrubbing could haveslowed down the ball bearings.

The temperature with the syrup may possibly have fluctuated during the research thus changing the viscosity of the syrup between assessments

As the ball bearings were eliminated some of the golden syrup can also have been taken so insufficient syrup could have been left pertaining to the various other ball bearings to reach port velocity before reaching the initial marker.

The stopwatches might not have been ended and began at the same time in each research. That minute was if the bottom from the ball approved the top of the marker and if it had certainly not been looked at horizontally every time then the benefits for finding the speed and its common may not had been accurate.

The screw measure could be clamped to different demands so the outcomes may include varied in which consistency was required.

Constraints

Since it was a human jugding when to have results, this experiment would not work for essential fluids of such a low viscosity that objects can pass all the markers prior to the eye could follow and track this. Computers and electronic sensors would be needed to replace a persons element in the experiment.

If the experiment could be done once again lasers can be used rather than my eyes as well as the markers. Better results could results from more accurate measuring devices would be necessary such as attach gauge micrometers that assess whilst clamping with the same pressure everytime.

Each try things out would be repeated more so as to get a morea ccurate average and the experiment would be done in a temp controlled environment so the viscosity remained precisely the same.
