Question 2 //25 Q (a) In figure below the flowing fluid is Helium at 20°C. D2 =6 cm D1=10 cm Neglect losses. If pl = 1400 kPa and the manometer fluid is Meriam red oil (SG = 0.827), estimate (a) p2 and (b) the gas flow rate in m/s.

Air flows steadily from a tank through the pipe inFig. . There is a converging nozzle on the end. Ifthe mass flow is 3 kg/s and the nozzle is choked, estimate(a) the Mach number at section 1 and (b) the pressureinside the tank.

I need answer within 20 minutes please please with my best wishes

Air is kept in a tank at pressure Po = 689 KPa abs and temperature To = 17°C. If one allows the air to issue out in a one-dimensional isentropic flow, the greatest possible flow per unit area is Blank 1 kg/m2-s. For air, Use R = 287 J/kg-K and Mol. Wt. = 29.1 *Express your answers in whole significant figure without decimal value and without unit*

When an oblique shock strikes a solid wall, it reflects as ashock of sufficient strength to cause the exit flow Ma3 to beparallel to the wall, as in Fig.  For airflow with Ma1 =2.5 and p1 = 100 kPa, compute Ma3, p3, and the angle ϕ.
