Answer:
Yes this claim is correct.
Explanation:
The shear stress at any point is proportional to the velocity gradient at any that point. Since the fluid that is in contact with the pipe wall shall have zero velocity due to no flow boundary condition and if we move small distance away from the wall the velocity will have a non zero value thus a maximum gradient will exist at the surface of the pipe hence correspondingly the shear stresses will also be maximum.
Answer:
A) See Attachment B) See Attachment C) 186.153
Explanation:
C) Per phase Voltage= 220/∛3
= 6.037
S=V²/Z
= (6.037)²/(0.01+i0.05)
= 62051.282-i310256.41
Active power losses per phase= 62.051kW
total Active power losses= 62.051×3
=186.153kW
Answer
C02 cartridges are compressed.
Explanation:
The C02 Cartridge will be used to power our dragsters by the compression inside of the bottle. Since C02 is a compressed gas inside of a small container, The pressure when released my provide enough force to move the dragster at high speeds. An example of this would be like an air soft gun. some air soft guns are used by small C02 Cartridges, which let out a strong burst of compressed C02, which fires the projectiles at very high speeds.
In a balanced three-phase Y-Y system, the source is an abc sequence of voltages and Van 100 20° V rms. The line impedance per phase is 0.6 + j1.2 N, while the per-phase impedance of the load is 10 + j14 Q. Calculate the line currents and the load voltages.
