Answer:
Reynolds number is 293068.43.
Explanation:
Step1
Given:
Water temperature is 98 °F.
Diameter of the pipe is 4 in
Length of the pipe is 870 feet.
Flow rate of water is 260 gallons per minute.
Calculation:
Step2
Water kinematic viscosity at temperature 98 F is ft²/s.
Find the velocity of the water as follows:
Q=AV
V=6.638 ft/s
Step3
Expression for Reynolds number is given as follows:
Here, v is velocity, is kinematic viscosity, d is diameter and Re is Reynolds number.
Substitute the values in the above equation as follows:
Re= 293068.43
Thus, the Reynolds number is 293068.43.

Answer:
NRO- Maintain intelligence satellites for U.S.
OCS- Train enlisted personnel to become an officer
Air force- provide counterintelligence training
Navy- provide control system operation procedures
Answer:
Option B (Starter Control Circuit) is the right option.
Explanation:
- This same switching is normally put upon this isolated side of something like the transmission Arduino microcontroller throughout the configuration that is using the ignition just to command the broadcast.
- It uses a secondary relay isolated to regulate electrical current throughout the solenoid starting system.
All other given options are not related to the given instance. So the above option is correct.
Answer:
The correct option is;
Materials and Components
Explanation:
The efficiency of fluid power is influenced by the components and the materials used to deliver the power of the fluid as such fluid power control are focused on
1) Advances in fluid power
2) Making use of the advantages
3) Making use of the other externally available technological advantages
4) Giving allowance for disadvantages
Areas of interest in advances in fluid power are;
a. Computer optimized flow
b. The use of new and improved materials/coatings
c. The use of components that save energy, such as intelligent supply pressure adapting systems
