I'm not sure how to work it out for time. but thanks for asking the right questions and making me think.

Hmm. Hadn't really thought to do that. I could definitely work out an equation for the velocity using the Bernoulli equation. especially if we used the outlet as h0 or 0 (as a reference height) and the level of the fluid as h. But i still feel as though the velocity within the smaller diameter...

ok sweet. but would the larger syringe not then "catch up" if it is subject to a greater weight force once the smaller syringe discharges a certain amount? is it just a case of the first syringe gets a "head start"?

yes. but the (y) value will be always changing in this situation so i didn't think to use it here. hydrostatics tells us that pressure throughout a fluid is constant yes? and that any pressure applied to an enclosed system will be felt by the whole fluid uniformally. so the fluid at the bottom...

Well I was thinking initially that there would be a greater force on the outlet of the syringe but I'm not sure that's right because the total amount of fluid above the syringe outlet is the same in both cases. I've read through my textbook but everything refers to fluid in/fluid out for fluid...

I don't have the diameters recorded, just the difference in height to the 5mL fill line which was 8mm. The fluid is water. I think I just had a lightbulb though. Can I use the equation of continuity in this situation even though it's not a closed system? If i do that, then my results make sense...

I ran it through 3 times each then calculated the average time. for the 5mL syringe, 3.51s, 3.44s, 3.50s. for 10mL syringe I had 4.09s, 4.08s, 4.10s. Both were consistent. If my understanding of the physics is correct then I will simply use them and then discuss how other factors may have...

Homework Statement More a report question but unsure where to put it. Take a 5mL syringe and a 10mL syringe (both filled to 5mL) with the plungers removed. Time how long it take to full drain each syringe Make a statement regarding your results. Homework Equations Fluid flow rate = volume /...
