Answer:
they are used for electrical currents so that they can flow along the appropriate wires in the circuit
Explanation:
Answer:
Yes, the flow is turbulent.
Explanation:
Reynolds number gives the nature of flow. If he Reynolds number is less than 2000 then the flow is laminar else turbulent.
Given:
Diameter of pipe is 10mm.
Velocity of the pipe is 1m/s.
Temperature of water is 200°C.
The kinematic viscosity at temperature 200°C is
m2/s.
Calculation:
Step1
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=64226.07579
Thus, the Reynolds number is 64226.07579. This is greater than 2000.
Hence, the given flow is turbulent flow.
Technician b says that hydrogen has better specific energy than fossil fuels. so technician b is correct.
<h3>
Does hydrogen have the highest specific energy?</h3>
- Although hydrogen has the highest energy density per mass of any fuel, it has the lowest energy density per unit volume due to its low ambient temperature density, necessitating the development of new storage technologies with the potential for higher energy density.
- Hydrogen is utilized as a rocket fuel and in fuel cells to generate power on some spacecraft because it is beneficial as an energy source or fuel due to its high energy content per unit of weight.
- Since hydrogen has a significantly higher energy content than fossil fuels, less of it is required to carry out any given task.

Answer:
1) a. Customers requiring AC electric power transmission for powering remote devices which may include a subsea transmission system where power is distributed to subsea devices
b. Customers that utilize commutator-type motors
2) The primary voltage is 150 volts
Explanation:
The parameters given are;
Number of primary winding,
= 50 turns
Number of secondary winding,
= 150 turns
Voltage in secondary winding,
= 450 volts
Voltage in primary winding = 
The relation between
,
,
and
is as follows;

Which gives;

From which we have;

The primary voltage = 150 volts.
