differential equation graphic solution

A fluid of constant density starts to flow into an empty and infinitely large tank at

8 L/s. A valve regulates the outlet flow to a constant 4L/s. Derive and solve the

differential equation describing this process over a 100 second interval.

This facility is for asking questions to help you understand matlab, such as what a particular error message means, or where to look in the documentation for a description of a kind of information. It is also common for the volunteers to help people debug programs that have already been written.

This facility is not for the volunteers to write homework for users
