Question

2 2 3 180 270 0 Pressure coefficient (Cp) distribution on a circular cylinder is shown above for three different flow cases (a, b, c). Comment on the characteristics of these flow cases. ***180° corresponds to the leading edge(front) of cylinder and Cº corresponds to the trailing edge(back) of the cylinder. Part b) 3 points Math the lettered (A, B, C) figures with the numbered (1, 2, 3) plots. Explain why? A) B) 1) 3) Tot Static pressure Sex Dyname Dynamic Dan

Answer 1

The gradual changing in the diameter of pipe reduces more dynamic pressure as compared to suddenly change of diameter.

Also, the irregularities present in the pipe decreases total pressure more as compared to smooth pipe.

(A) - (2)

(B) - (1)

(C) - (3)
