title of lab is fluid and pressure
hypothesis: fluid pressure varies with size of opening
aim: to determine whether fluid pressure varies with size of opening

i need help with the expected results, discussion, variables: (manipulated, responding and constant), sources of error, limitations and precautions

would anyone plz help me in these areas plz??

to have an idea of what the lab looks like.. its a set up of 4 different regular shaped plastic containers with holes of radii 1mm, 5mm, 10mm and 20mm in each container such that the center of the hole is 5cm from the ground. im suppose to block the hole and fill the container completely then unblock the hole and measure the maximum distance the water reached.

one expected result i have so far is that the diameter is inversely proportional to the flow rate; the smaller the hole the further the water will go.

for my limitations i have: altitude affects the distance travelled by the water.
the for precautions i have: it should be performed outside and wind might affect the distance travelled by the gush of water and leave the container empty.
for my variables i have: manipulated- the amount of water used, responding- the flow rate and the amounr of water released and for constant- the size of the holes, nature of the fluid

There will definitely be uncertainty in measuring the radii of the holes and with the measurement of the hole height from the ground. You could also talk about uncertainty in "(un)blocking" the hole - have you thought about how you could do this accurately? Could you use electronic equipment to automatically do this for you?

Haha I did this as part of my my advanced higher investigation. You should check out Bernoulli's equation as it explains a lot. I could email you the investigation if you want. It's about 50 pages long and got 24 out of 25, and has everything you need in it lol.

no i cannot use anything electronic i dont think i can.. also yes i have thought about how i could do this accurately but i've been thinking what if i thought about it and then when i bring in the draft the teacher said that its unacceptable so im thinking outside of the box now
