PLEASE HELP! A tap is used to fill the container at a constant rate. Draw a sketch of the graph of height of water level against time, given it take 60 seconds to fill the container. Use a scale of 1cm to represent 5 seconds on x-axis and 1cm to represent a height of 1 cm on the y-axis.

In the center, there is a cuboid.. And above and below it are parts of cone? Or, they are just some irregular shapes?

OpenStudy (ujjwal):

No, that's not a cuboid, i guess.. That's a cylinder probably..

OpenStudy (anonymous):

Yes, that's a cylinder.

OpenStudy (anonymous):

I know that the gradient of the graph would increase for the first shape, would be constant for the second and decrease for the upper most shape. But I can't figure out how to do the calculation so as to plot on the graph. >_<

OpenStudy (anonymous):

if its filled at a constant rate, why is the shape of the graph like that?

OpenStudy (anonymous):

Because the cross-sectional area differs along the length of the container. @javawarrior

OpenStudy (anonymous):

and what are you trying to find?

OpenStudy (anonymous):

I have to plot the graph. So I want to find out the time it would take to fill each part.

OpenStudy (ujjwal):

Do you have individual heights for each part?

OpenStudy (anonymous):

No, individual lengths are not mentioned in the book. But by looking at the figure, I assumed they must be 3, 2, 3.

OpenStudy (anonymous):

did you do the graph by doing your own experiment?

OpenStudy (anonymous):

No, the heights and cross-sectional areas all different so I have no idea as to which value to use to compare the time taken to fill each section.
