As shown in figure Q1, air flows through a converging nozzle from a large tank and into a receiver. At section 1, the temperature is 350 k, the pressure is 320 kPa (abs), and the flow the flow area is 0.40 m?. The pressure in the large tank is 360 kPa (abs). Nozzle exit area is 0.30 m?. Air flow is assumed to be steady and isentropic in the converging nozzle. Express answer at least 3 significant figures. Take K as 1.40 and R as 0.287 kJ/kg.K Determine: a) The mach number at Section 1. b) The mach number, pressure and velocity at the exit. c) The mass flow rate through the nozzle.

Q3- Air flows from a reservoir and enters a uniform pipe with a diameter of 0.05 m and length of 10 m. The air exits to the atmosphere. The following conditions prevail at the exit: P2 = 1bar, temperature T2 = 27°C and M2 = 0.9. Assume that the average friction factor to be f = 0.004 and that the flow from the reservoir up to the pipe inlet is essentially isentropic Estimate the total temperature and total pressure in the reservoir under the Fanno flow model. %3D M2 0.9 D-0.05 m] L=10 m Po=?
