X Your answer is incorrect. The figure below provides steady-state data for water vapor flowing through a piping configuration where V1 = 35 m/s and T1 = 200°C. At each exit, the volumetric flow rate, pressure, and temperature are equal. P2= 4.8 bar T = 320°C Water vapor (AV)2 = (AV)3 V, T A1 = 0.2 m? Pi = 5 bar 3 P3 = 4.8 bar T3 = 320°C Determine the mass flow rate at the inlet and exits, each in kg/s. i 25.78 kg/s = i 12.89 kg/s m3 = i 12.89 kg/s
PROBLEM 2 Consider a firefighter who is standing on a ladder and spraying water with a hose into Chief Inspector Jacques Clouseau's (Figure 3a) third-story apartment. A diagram of the hose/nozzle used by the firefighter is shown in Figure 3b. Assume the nozzle has little effect on the flow in the hose and water in the hose/nozzle is incompressible. The temperature of the water in the hose is 15 °C. (a) Chief Inspector Jacques Clouseau investigating the cause of the fire in his apartment. water hose diameter=10cm outlet diameter=5cm Figure 3 个个个 outlet velocity=6ms¹ (b) Fire hose/nozzle used to extinguish the fire in Inspector Clouseau's apartment.
Question 3: a) In a '72.77' mm diameter pipeline conveying air, the inlet Mach number is measured to be $0.5198'. Find the length of the pipeline at which the flow conditions become sonic. Assume standard air properties and the average friction factor obtained from independent tests is 0.02. Also obtain Mach number at 1 m from the inlet of the pipe.
Q4. Water from a reservoir is conveyed via a pipeline of constant diameter and 1000m length to a turbine situated 90m below the reservoir surface level. The velocity of flow through the pipeline is 5m/s and the energy loss due to friction in the pipeline is 200J/kg. The water leaves the turbine at atmospheric pressure (100 kN/m2) and with negligible velocity. Assuming an efficiency of 85% for the turbine, determine: a). Pipeline diameter b). Pressure at entry to turbine c). Turbine power output. Take f = 0.025
a turbojet on a test stand air at inlet has density of 1.1 kg/m^3 at the exit gas has higher velocity and higher temp, but pressure is the same. inlet area is 0.5m^2 and free stream velocty is 200m/s. fuel air mix is 1:15 at exit, engine area is 0.3m^2, gas velocity 800m/s Determine the density of gas at exit and evaluate reaction forces to hold test stand Turbojet Engine V1 V2 P2 A1 A2 Test Stand
Q4) The nozzles receive steam at 1.75 MPa, 300 °C, and exit pressure of steam is 1.05 MPa. If there are 16 nozzles, find the cross-sectional area of the exit of each nozzle for a total discharge to be 280 kg/min. Assume nozzle efficiency of 90%. If the steam has velocity of 120 m/s at the entry to the nozzles, by how much would the discharge be increased?
