Q 5 please
DC 28 29 Questions 28 5. A convergent nozzle has an inlet area of 100 mm2 and an exit area of 50 mm2. The fluid flowing through the nozzle is air, having a density of 1.2 kg/m3 and a velocity of 20 m/s at the inlet. If the density at the outlet is 0.18 kg/m3, calculate the mass flow rate and the outlet velocity 6. Water flows through a circular pipe A with a constant diameter of...

2. An aircraft with a single turbojet engine (with an inlet area of 1 m2) is flying at cruising condition with a flight Mach number of 0.7. The ambient temperature and pressure are 250 K and 100 kPa, respectively. The engine compressor pressure ratio is 12, and the turbine inlet temperature is 1200 K. Assume all mechanical components are operating at isentropic condition and the specific heat can be considered a constant (throughout the entire engine) of 1 kJ/(kg K)....

At steady state, air at 200 kPa, 325 K, and mass flow rate of 1.0 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. The inlet cross-sectional area is 6 cm2. At the duct exit, the pressure of the air is 100 kPa and the velocity is 300 m/s. Neglecting potential energy effects and modeling air as an ideal gas, determine a. the velocity of the air at the inlet, in m/s. b. the temperature of the...

Please help me thanks.
A horizontal pipe is shown in the figure below. At the inlet (Point 1), the radius of the pipe is 4 cm and the velocity profile is given by: V = 16- y2 cm/s. At the outlet (Point 2), the radius is 2 cm and the velocity changes to a uniform profile, as shown in the figure. If the viscosity of the liquid inside the pipe is 0.07 [Pa s] and its density is 1030 kg/m3,...

1. Water enters the constant 130-mm inside-diameter tubes of a boiler at 7 MPa and 65°C and leaves the tubes at 6 MPa and 450°C with a velocity of 80 m/s. Calculate the velocity of the water at the tube inlet and the inlet volume flow rate. [5-14] 2. Air enters a nozzle steadily at 50 psia, 140°F, and 150 ft/s and leaves at 14.7 psia and 900 ft/s. The heat loss from the nozzle is estimated to be 6.5...
