With the help of the compressor, the air at 300 K and 101 kPa is compressedto 430 kPa and fed to a pipeline with an inner radius of 0.015 m. The velocity of the air in the compressor inlet is given as 5 m / s. The velocity at the point where the air is fed into the pipeline has been measured as 32 m / s and the temperature as 510 K. Calculate the compressor power (kW) by assuming that the compression process in the compressor is adiabatic and that the air exhibits ideal gas behavior (Cphava = 1.005 kJ / kg.K).

Please help me to complete the tables and provide a computations using superposition theorem of circuit in figure 8.1. superposition: -states that the voltage across or current through an element in a linear circuit is the algebraic sum of the voltage across or current through that element due to each independent source acting alone. Objective: this laboratory exercise will check if it will uphold superposition theorem. Its application to find circuit currents and voltages will be experimented. Questions: 1. Show the theoretical computation using superposition theorem of circuit in figure 8.1. 2. Does the measured parameters applied to superposition? Explain. 3. What are your conclusions and recommendations?

-A transmission line has a span of 150 m between the level supports. The conductor has a cross-sectional area
-A transmission line has a span of 150 m between the level supports. The conductor has a cross-sectional area of 2 cm^2. The ultimate strength is 5000 kg/cm^2. The specific gravity of the material is 8·9 gm/cm^3. If the wind pressure is 1·5 kg/m length of conductor, calculate the sag at the center of the conductor if factor of safety is 5. -A transmission line has a span of 250 m between supports, the supports being at the same level. The conductor has a cross-sectional area of 1·29 cm^2. The ultimate strength is 4220 kg/cm^2 and factor of safety is 2. The wind pressure is 40 kg/cm^2. Calculate the height of the conductor above ground level at which it should be supported if a minimum clearance of 7m is to be kept between the ground and the conductor.

B.The propeller blades go into a high pitch high RPM configuration. C.The propeller blades go into a high pitch low RPM configuration. 2 points QUESTION 6What happens to the propeller blades when the pilot pulls the propeller controls back?A.The propeller blades go into a low pitch low RPM configuration. B.The propeller blades go into a high pitch low RPM configuration. C.The propeller blades go into a low pitch high RPM configuration. 2 points QUESTION 7What device helps the propeller maintain a constant speed?A.The propeller counter weightdB.The fly weightsC.The propeller governor 2 points QUESTION 8How would the pilot feather the propeller?A.Place the propeller controls in the middle of the control quadrant.B.Pull the propeller controls full aft.C.Place the propeller controls full forward2 points QUESTION 9When the oil goes from the propeller to the engine, the propeller blades will automatically feather. What keeps the propeller blades from feathering on the gound when the engine is shut down?A.feathering blockersB.spring loaded anti feathering locks or pins C.blade actuators2 points QUESTION 10What is the name of the valve that regulates the oil to and from the propeller to adjust the propeller blades?A.universal valveB.pilot valveC.oil valve2 points QUESTION 11What is the purpose of the propeller governor fly weights? A.The flyweights respond to the speed of the propeller conteracted by the speeder spring pressure set by the pilot. The flyweights senses propeller speed changes through lateral force and moves the pilot valve to either allow oil to leave the propeller or enter the propeller. B.The flyweights respond to the speed of the propeller conteracted by the speeder spring pressure set by the pilot. The flyweights senses propeller speed changes through centrifugal force and moves the pilot valve to either allow oil to leave the propeller or enter the propeller. C.The flyweights respond to the speed of the propeller conteracted by the piston spring pressure set by the pilot. The flyweights senses propeller speed changes through centrifugal force and moves the pilot valve to either allow oil to leave the propeller or enter the propeller. 2 points QUESTION 12What is the benefit of a feathered propeller?A.A feathered propeller will reduce propeller drag on an engine that is producing power thereby allowing the running engine to possibly keeping the airplane airborne and climbing. B.A feathered propeller will increase propeller drag on the engine that is no longer producing power thereby allowing the running engine to possibly keep the airplane airborne and climbing. C.A feathered propeller will reduce propeller drag on an engine that is no longer producing power thereby allowing the running engine to possibly keep the airplane airborne and climbing.
