What are the parallels between water flow in a pipe circuit and electric current flow in a DC electric circuit

The flow in a pipe is the same principle as an electric current, (volts) whether DC or AC. Of course the more pressure in the pipe the similarity would be said of a current..increase the resistance (narrow pipe) increase the resistance in the wire (smaller diameter). Which will increase the pressure at the end Amps.

John C is confused. The flow (current) of water in, for instance, gallons per minute, is analagous to current (measured in amperes) in the electrical circuit. The pipe's diameter is analagous to the d.c. circuit's resistance (measured in ohms). The flow in either case is proportional to the pressure applied across each system, for instance pounds per square inch for the hydraulic one, and volts for the electrical one.

be as specific as possible; Water -------------------------- Value-------------------Electricity Water tower (in gallons)--- potential----------------volts GPM (gallons per minute) - strength of movement -amps Dam -------------------------Resistance ------------ohms

Voltage = Pressure Current = Flow rate Resistance = A flow restriction, like a pinch-point A DC source is like a pump.

The equations for describing these flows are identical in nature: for water flow use the continutiy equation: Q=VA Where Q is the quantity of fluid, A is the area of the conductor and V is the velocity of flow, persons versed in electrical theory will immediaely recognize that this is a statement of Ohm"s law E = IR mechanical engineers might see a similarity with s = at or F= ma while civil engineers will recall stress = M x section modulus. All of this is a simple indication that mechanics is mechanics regardless of the material.
