- 1) One of the common devices used in Engineering is a nozzle to transfer fluids such as air. Assume a steady-state flow and air as an ideal gas with the following parameters: Inlet: Mass flow = 2.1 kg/s V1 = 0.72 m³/kg T1 = 600 K A = 240 cm? Outlet: V2 = 2.7 m³/kg A2 = 40 cm2 a) What is the air pressure at the outlet. b) What is the velocity of the airflow at the inlet. c) What is the velocity of air at the outlet.2. A rigid tank (volume = V) containing an ideal gas is initially at T, and P. At time zero, an exit pipe (area = A) is opened and gas flows out of the tank at velocity v = K(P – Pam)2, where P is the pressure in the tank, Patm is the pressure of the atmosphere outside the tank, and K is a constant. The temperature of the gas in the tank is maintained at T, during the process. The pressure and the temperature of the gas exiting the tank are Patm and T1, respectively. Assume that, inside the tank, the pressure and specific volume do not vary with position. %3D A. Derive a differential equation for the tank pressure P as a function of time t. B. Determine the time required for the tank pressure to reach Patm:find thermodynamic system borders and surroundings
