Using the same input design data for the IFR turbine given in Problem 5 and given that the total-to-static efficiency is 0.8, determine
a. the stagnation pressure of the gas at inlet and
b. the total-to-total efficiency of the turbine
Problem 5
The radial-inflow turbine in Problem 3 is designed for a specific speed Ωs of 0.55 rad. Determine
a. the volume flow rate and the turbine power output;
b. the rotor exit hub and tip diameters;
c. the nozzle exit flow angle and the rotor inlet passage width diameter ratio, b2/D2.
