Hello! I'm modelling the pump with controlled oil flow rate.

I'm using the "fixed-displacement pump" block with the signal builder.

The thing is that I don't yet understand the structure of this block. What should be the signal value to create the flow rate that equals to 0.1389 m3/sec? (see the fig.)

Maybe there's more simple way to model this?

Do you want to use the Fixed Displacement Pump or do you want to just implement a constant flow rate source? If its the first case, start by taking a look at this example, if its the second case use a Hydraulic Constant Flow Rate Source block instead.
