    V-3. Air flows at steady state through a horizontal, well-insulated, constant-area duct whose diameter is 0.75 in. At the inlet, p1 = 55.9 lbf/in.2, T1 = 7200R, and the velocity is 9 ft/s. The temperature of the air leaving the duct is 700°R. Determine (a) the velocity at the exit, in ft/s. (b) the pressure at the exit, in lbf/in.2 (c) the magnitude of the net horizontal force exerted by the duct wall on the air, in lbf. In which...

    Air flows through a constant area duct. The pressure and temperature of the air at the inlet to the duct are P1 = 100 kPa absolute, and T1 = 298 K, respectively. Inlet Mach number is M1 = 0.1. Heat is transferred to the air as it flows through the duct and as a result the Mach number at the exit increases. a) Find the pressure and temperature at the exit, while the exit Mach number changes between M=0.2 to...

    1. (15 pts) A converging-diverging nozzle has an area ratio of 2, i.e., the exit (or duct) area is 2 times the throat area, which is 80 cm2. The nozzle is supplied from a tank containing air (y 1.4 and R 287 J/kg K) at 100 kPa and 300K. For both cases shown in Fig. , find the maximum mass flow possible through the nozzle and the range of back pressures over which the mass flow can be attained. For...

    Air, at po = 160 lbf/in2 and To = 300°F, flows isentropically through a converging-diverging nozzle. At section 1, where A1 = 288 in2, the velocity is V1 = 2068 ft/s. Calculate the inlet Mach number (Ma1) and the throat area (A*). The inlet Mach number is-------- . The throat area is---------- ft2.es Determine the inlet pressure (p1) and the mass flow rate (m.). Round the final answer to three decimal places. The inlet pressure is ----------- lbf/ft2. The mass...
