1.Adiabatic process Thermodynamics process in which no heat is transferred to or from thee system during the process. A reversible adiabatic process is called isentropic process. 2.Airfoil A streamlined form bounded principally by two flattened curves and whose length and width are very large in comparasion with thickness. 3Airfoil drag force: Force acting on the airfoil in the direction of motion represnets frictional forces. 4.Air rate Kilograms per second of airfloebrequired per net horse powrer developed . Also called Flow rate. 5.Angle of attack The angle of inclination of the non symmetrical airfoil with the direction of the undisturbed flow. 6.Angle of deviation The difference between the fluid angle at out and the blade angle at outlet.This may be positive or negative .Sometimes called Deviation. 7.Angle of incidence The difference between the fluid angle at inlet and the blade angle at inlet. 8.Aspect ratio of blade Ratio of blade height to blade...
