Hi pasmith, Many thanks for your explanation. I can't say that I fully understand it, particularly the solving of the 'linear recurrence relation', and I cannot see a way that I can use this information in practice. Looking at the problem from another perspective, if I know the rate of...

Hi Haruspex, I thought that I'd explained the problem previously? Anyway I'll explain again...I have a container (hopper) with a material infeed that I know (i.e. kg/s). The output from the hopper is controlled by a slide valve opening & closing. The discharge from the hopper goes into a...

I'm having difficulties trying to establish the best approach to create a mathematical model of a process that has a combined continuous and discrete (batch) element to it. I explain as follows: The system is a hopper (vessel), open to atmosphere, with dry granular material being fed in by...
