The equations for calculating the velocities of a fluid and its pressure on a radial-axial flow turbine blade with variation of slope angle of individual blade sections are refined. The velocities of the fluid oriented perpendicular to the blade plane and in tangential and radial directions and the pressure of the fluid in tangential direction are expressed for a radial-axial flow turbine by similar equations and differ only in slope angles of the blade sections. The equations for determining the pressure in the direction perpendicular to the blade plane and in radial direction differ in both slope angles of the blade sections and in calculating equations.
