(a) Circuit diagram of a 2-input, 1-output fork topology where R1 and R2 are selectively chosen for desired operational output. (b) Equivalent hydraulic circuit where only R1 and R2, the selected resistance components reasonably contribute to mixing ratio and wire elements are construed as “parasitic”, or negligible. Note that the current source symbol represents a syringe withdrawing solutions through the inlets to the outlet. (c) Equivalent hydraulic circuit with syringe attached to output end to demonstrate experimental setup.
