Description : Why thermal efficiency of I.C. engines is more than that of gas turbine plant ?
Last Answer : In I.C. engine maximum temperature attained is higher than in gas turbine.
Description : Why gas turbine power plant needs efficient compressor ?
Last Answer : Because a large portion of turbine work is eaten away by compressor and its inefficiency will affect net power output and cost of generation.
Description : What Is A Stage In A Steam Turbine?
Last Answer : In an impulse turbine, the stage is a set of moving blades behind the nozzle. In a reaction turbine, each row of blades is called a "stage." A single Curtis stage may consist of two or more rows of moving blades.
