- You are being tasked as a wind tunnel engineer to investigate the performance of newly designed high-speed wind tunnel in UPNM. An exhaust gas flows through a nozzle where the inlet area is 5,000 cm2.At this inlet, the gas has a velocity of 1,200 m/s, temperature of 1,500oC,and pressure of 6,000 kPa. Initial measurement revealed that the pressure at the exit of the wind tunnel is 100 kPa. Based on this information, analyze and investigate ; i. Mach number at inlet of the nozzle ii. The velocity of gas at exit iii. The area of the nozzle at exit Take specific heat ratio for the exhaust gas, ? to be 1.7 and the gas constant, R to be 205 J/kg.Derive a control volume form of the second law of thermodynamics. Suggest some practical uses for your relation in analyzing real fluid flows.Q/ ture or false -The flow curves are classified according to the number of reactors and the mechanism of separation or non-separation in the cores
- Fluid Mechanics. Pb # 5: Explain Cavitation in Pumps. Support your answer with neat sketches/graphs.According to Bernoulli’s principle, if the fluid pressure is higher, the volume flow rate of an incompressible fluid will be higher as well. True or FalseSAE 50W oil at 20°C flows from one tank to another through a tube 220 cm long and 5 cm in diameter. Estimate the flow rate in m3/hr if z1 = 2 m and z2 = 0.8 m. For SAE 50W oil, take ρ = 902 kg/m3 and μ = 0.86 kg/m-s. Take π = 22/7. The flow rate is m3/hr.
- Air, assumed to be a perfect gas from Table A.4, fl owsthrough a long, 2-cm-diameter insulated tube. At section 1,the pressure is 1.1 MPa and the temperature is 345 K. Atsection 2, 67 meters further downstream, the density is1.34 kg/m 3 , the temperature 298 K, and the Mach numberis 0.90. For one-dimensional fl ow, calculate ( a ) the massfl ow; ( b ) p 2 ; (c) V 2 ; and ( d ) the change in entropy between1 and 2. ( e ) How do you explain the entropy change?Steam enters a horizontal turbine at 350 lbf/in 2 absolute,580 ° C, and 12 ft/s and is discharged at 110 ft/s and 25 ° Csaturated conditions. The mass fl ow is 2.5 lbm/s, and theheat losses are 7 Btu/lb of steam. If head losses are negligible,how much horsepower does the turbine develop?For supersonic and hypersonic wind tunnels, a diffuser efficiency, ηD,can be defined as the ratio of the total pressures at the diffuser exit andnozzle reservoir, divided by the total pressure ratio across a normal shockat the test-section Mach number. This is a measure of the efficiency ofthe diffuser relative to normal shock pressure recovery. Consider asupersonic wind tunnel designed for a test-section Mach number of 3.0which exhausts directly to the atmosphere. The diffuser efficiency is 1.2.Calculate the minimum reservoir pressure necessary for running thetunnel.
