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 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.
