An axial compressor is designed to operate at a rotor speed of 15000 rpm and an inlet stagnation temperature of $300 \mathrm{~K}$. During compressor testing, the inlet
stagnation temperature of the compressor measured was $280 \mathrm{~K}$. What should be the rotor speed for the compressor to develop the same performance characteristics
during this test as in the design condition?
(A) $14000 \mathrm{rpm}$
(B) $14491 \mathrm{rpm}$
(C) $15526 \mathrm{rpm}$
(D) $16071 \mathrm{rpm}$
