i just need final answer The tank is filled with air at 20°C and 139 kPa in stationary condition. Air is leaving the tank with flowing in anozzle under steady-state condition. The flow is under isentropic and subsonic condition. The nozzle exit area is28,1 cm2. After leaving from the nozzle, air strikes a vertical plate. Define the force [N] required to hold the platestationary. (Note: Assume Pe=1 atm, kor=1.4, Ric=287 J/kg.K)

(b) Air flows through a cylindrical duct at a rate of 2.3 kg/s. Friction between air and the duct and friction within air can be neglected. The diameter of the duct is 10cm and the air temperature and pressure at the inlet are T₁ 450 K and P₁ = 200 kPa. If the Mach number at the exit is Ma2 determine the rate of heat transfer and the pressure difference across the duct. The constant pressure specific heat of air is cp = 1.005 kJ/kg-K. The gas constant of air is R = 0.287 kJ/kg-K and assume k = 1.4. -
Q1: A converging-diverging frictionless nozzle is used to accelerate an airstream emanating from a large chamber. The nozzle has an exit area of 30cm² and a throat area of 15cm². If the chamber temperature is 500K, and the back pressure is 101kPa, calculate the following: a. Minimunt chamber pressure (po) to choke the nozzle. b. Mass flow rate for a chamber pressure (po) of 400kPa. c. Mass flow rate for a chamber pressure (po) of 105kPa.
Please show your complete solution. Thank you! Air flows in a steady flow manner through a converging tube. At the inlet the pressure is 690kPaabs and the density is 0.838 kg/cu.m. If air enters with a volume flow of 125 cu.m per min at the rate of 94 m/min and the exit section has a diameter of 350mm, determine a.) the mass flow rate, kg/min b.) the diameter of the entrance section and c.) the exit velocity. Assume that the density is constant.
