I am new here and I am seeking for help:) Thank you so much.

In engineering, electrical formula often analogy to mechanical formula.

eg. power[W] = pressure x volume flow rate vs power[W] = voltage x current

My question is could we make the simplest unit between electrical and mechanical?

1. mechanical pressure [N/m2] = voltage pressure [V]

1a. P=F/A=FR[resistance] ; V=IR

1b. Power[W]= force x velocity = force x distance/time; Could make analogy to electrical?

1c. Energy[J] = pressure x volume = pressure x area x distance;

2. volume flow rate[m3/s] = current[A]/[C/s]

2a. volume flow rate = area[m2] x velocity[m/s] current to ?

For 1a. where force = current = volume flow rate?
