The depth of water in a glass at each time is measured, as coloured water flowed in at a constant rate. The results are tabulated below:
T (s) V (mL)
10 2
20 2.6
30 3
40 3.3
50 3.5
60 3.7
70 3.9
80 4.1
90 4.3
100 4.4
1) Determine the depth of water in the glass as a function of time. Assume that depth at t=0 is 0cm.
2) Using geometry, determine a theoretical equation for the depth as a function of time.

Best ResponseYou've already chosen the best response.0Wouldn't you need to know the width of the glass?

Best ResponseYou've already chosen the best response.0I guess "V" is supposed to be depth.....

Best ResponseYou've already chosen the best response.0But V is in units of milliliters . . .

Best ResponseYou've already chosen the best response.0It can be done keeping the base area of the glass as a variable expression. Maybe assume it is a cylinder and let r = radius?

Best ResponseYou've already chosen the best response.1the radius is 3.2cm and the depth is 4.8cm

Best ResponseYou've already chosen the best response.0@CliffSedge you just keep answering. you too are useless like me ... as you said me earlier, you could be suspended soon.

Best ResponseYou've already chosen the best response.0A radius of 3.2 cm implies a base area of π(3.2)^2 cm^2. Divide the volume by that area to get the height.

Best ResponseYou've already chosen the best response.1for the V(ml), it is meant to be D(cm)

Best ResponseYou've already chosen the best response.0Questions 1 and 2 seem to be the same question now.... From 40 to 90, depth goes up by 0.2 per 10 secs so if we take that as the "real" rate Depth = 0.02t
