it depends on the operating point as to what the tube will dissipate. If you mean the maximum rated plate dissip. of the different types, this information is stated in the tube data sheets (see duncan amp's tdsl).A 6550 is rated for 35W max plate dissipation. So typically, you would find many running in the 20-30W range.
oh, thats just the plate, btw. Some tubes with large heater/filament currents can put out 10-20W additional. And pentodes/BTs will add a bit more from their screen dissipation.
