I have a load cell which is measuring a product discharging into a bin.

the rate at which the bin fills is variable at the start and end of the

cycle and I get the

following readings of load (M = Mass, t = Time) at each given time in

seconds in the cycle.

t = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ]

M = [0 0.5 0.6 0.9 2 3 4 5 6 7 8 9 10 10.3 10.4 10.5 ]

I can plot this to show the output from the load cell with no problems.

How do I process the data, to give me the mass flow rate in Kg/sec at any

given point in time

I want to have a graph showing Kg/s Vs time so that at any given time in the

cycle the MFR can be found.

I'm pretty sure that this has something to do with finding the gradient at

any given point on the curve??

there must also be some differentiation inthere somewhere too...

can someone guide me to an answer??
