I think that the additional weight on the water on the surface of the outer airplane body increases friction with the air, and also weight of the aircraft. But does the fuel consumption increase? And by how much?

Fun fact. In the days before high-bypass turbofan engines, water was deliberately injected into jet engines to cool down the combustion chamber and increase thrust: https://en.wikipedia.org/wiki/Water_injection_(engine)#Use_in_aircraft
So they were part steam engine. Cool.
Never thought of it that way, but yeah, you could say that.
Damn what a rabbit hole and TIL
