Question

1.The following information is known about the steady flow of air through an adiabatic system: At section 1; T_1 = 556 R, p_1=28.0 psia At section 2; T_2 = 70 F,? T?_t2 =109 F, p_2 =18 psia (a) Find M_2 , V_2 , p_t2 . (b) M_1 , V_1 , p_t1 . (c) Compute the area ratio A_2/A_1 . 2. Two venture meters are installed in a 30-cm-diameter duct that is insulated. The conditions are such that sonic flow exists at each throat; i.e., M_1 = M_4 = 1.0. Although each venturi is isentropic, the connecting duct has friction and hence losses exist between sections 2 and 3. p_1=3 bars absolute and p_4= 2.5 bars abs. If the diameter at section 1 is 1.5 cm and the fluid is air: (a) Compute Ds for the connecting duct. (b) Find the diameter at section 4. ***missing picture for problem (2), looks like 4 different points through two diverging nozzles. Flow from left to right, point one is at the middle of the first nozzle, point 2 in at the very end of the first nozzle, point 3 is at the very beginning of the second nozzle , and point 4 is in the middle of the second nozzle.
