Hi,
I'm thinking of a water pump with only the valves as moving parts - the compressed air simply displaces water from a cylinder. I understand it's a solution for where it's easier to deliver compressed air than electricity to the pump site.
My question is: where are the energy losses in the compressed air power transmission? The context is in comparison to turning shaft of a water pump by coupling to an electric motor.
I worried for a bit that the heat at head of air compressor is all wasted energy, but is that relevant if most of energy was latent heat from the air rather than from motor that drives the compressor?
I figure it must be an inefficient system otherwise I'd see a lot of these pumps around.
